Does anyone know of the drawbacks and future plans anything to look out for?
Ask any of these persons http://hif.lbl.gov/VNLstaff.htmlKidphysics said:Does anyone know of the drawbacks and future plans anything to look out for?
You can google this information yourself.Kidphysics said:Joseph, do you know the current status of NDCX-II
But NDCX-II is only a one little part of very extensive Heavy Ions Fusion program intended only for checking of possibility of focusing of very intense pulse ion beams by background plasma (plasma column) and nothing more.
There in heavy ions fusion is intended to use Cesium ion beams and not Lithium.
Although the cost reduction program and other parts of the program aimed at fusion
energy were discontinued in 2003, accelerator development was fortunately able to
continue at a modest budget level in support of high-energy-density physics research.
Most recently, Recovery Act Funds have allowed the construction of the NDCX-II
accelerator. NDCX-II incorporates some features of a power plant driver, albeit at
small scale, and so it provides a very good test bed for the validation of theory and
simulation. While NDCX-II is not the ideal first step if inertial fusion energy were the
primary goal instead of high-energy-density physics research, it will help to resolve
some of the critical issues needed to determine heavy-ion fusion’s feasibility
Ask any of these persons http://hif.lbl.gov/VNLstaff.html
All they are members of Virtual National Laboratory (VNL) sponsored by DOE.
54 persons with annual salary not less than 60'000 USD (up to 100'000 USD/y). So DOE spends only on salary about 3'500'000 USD per year.
Strange statement. As if to use Google with key words “Heavy Ions Fusion DOE” one of the first links you will get is: http://www.ornl.gov/info/news/pulse/no368/feature.sht dated at July 30, 2012.the_wolfman said:As I stated earlier, the US stopped funding heavy ion fusion driver research in 2003. Also the primary goal of NDCX-II is to support HEDP research NOT Heavy Ion Fusion.
A three-lab “virtual laboratory” to study heavy-ion fusion
DOE’s Lawrence Berkeley National Laboratory is home to the second-generation Neutralized Drift Compression Experiment,, whose member institutions also include DOE’s Lawrence Livermore National Laboratory and Princeton Plasma Physics Laboratory.[/QOUTE]NDCX-II, designed and built by the Heavy Ion Fusion Science Virtual National Laboratory (HIFS VNL)
So, as you can see, the program was not canceled but only is weakly started yet.
Why weakly? We can discuss it. But that is the fact. Despite another fact of last update of Virtual National Laboratory's site. Never interested in that but try to search also with the help of key words "nonneutral plasma". You would find a lot of papers dated in 2012, 2011, 2010 and so on (so later than "cancelation date of project) written by the members of Virtual Lab
I am familiar with one person who is very qualified physicist born in Russia. So, I have some insider information too (only about status of program).
See also the: http://fsc.lle.rochester.edu/pub/HEDLP/presentations/Barnard.pdf dated at 2008 (also later than 2003)
I have never heard about Russian-Germany collaboration in this branch. Heard about Light Ions Fusion program and some hardware built in Karlsruhe University under leadership of Dr. Bluhm.
Strange statement.
line 2422 on 2-37 I tend to believe them.The U.S. Department of Energy supported the development of heavy-ion accelerators
for fusion power production until 2003
How they are involved if after mentioned by them date 2003 another scientists working in three largest NATIONAL Labs say that they still working?the_wolfman said:The report is a peer reviewed document written and reviewed by a number of scientist involved in inertial confinement fusion.
Also when they make comments such as:
line 2422 on 2-37 I tend to believe them.
There are a handful of experiments that do research relevant to heavy ion fusion
NDCX-II is only a one little part of very extensive Heavy Ions Fusion program
The Heavy Ion Fusion Science Virtual National Laboratory is a collaboration of LLNL, Lawrence Berkeley National Laboratory, and the Princeton Plasma Physics Laboratory. The LLNL group is part of the Fusion Energy Sciences Program within the Physics Division of the Physical and Life Sciences Directorate. Our principal funding is from the DOE Office of Fusion Energy Sciences (OFES) program in High Energy Density Laboratory Plasmas (HEDLP) and related topics. Most of the group members maintain their principal offices at LBNL.
While NDCX-II is not the ideal first step if inertial fusion energy were the
primary goal instead of high-energy-density physics research
Much of the recent work on heavy ion drivers have been with an emphasis to enable HEPD research. WDM is a branch of HEPD.Recent history:emphasis on warm dense matter (WDM) physics
required innovations (applicable to HIF, too!)
the_wolfman said:First there are some usually some funds in the DOE budget to develop alternative or innovative concepts. The pools of money for this projects are significantly smaller than the main thrusts. But it is a source that HIF researchers can tap.
As far as I know, little or no HIF research is being funded by the innovative concepts pot of money. At least the pot of money that I am aware of. I think the ICF innovative concepts pot was cut or was restructured 5-6 years ago, but I could be wrong. I do know that the ICF people stopped going to the innovative fusion concepts meetings around that time. In fact, the magnetic confinement innovative concepts funding has also changed priorities to be MUCH more tokamak specific, though many of the existing projects recast/reword their focus to remain 'relevant' to the new focus.
I had a friend who did his dissertation on HIF - I can ask him to see what the current news is if you'd like.
So, not in 2003 as you stated earlier?the_wolfman said:I think most of the ICC projects were cut around 2010-2011.
What is slow in inertial confinement?kinkmode said:They were researching things like fast ignition.
Laser ignition failed with NIF (national ignition facility). And all processes in inertial confinement are rather fast. In opposite case "inertial" is impossible.kinkmode said:I don't recall what fast ignition exactly was. The last talk I heard on it was 5 years ago. It was something along the lines of decoupling the ignition and compression phases.

I am afraid that only Hollywood related activity (Star track in the Darkness) is still actual for NIF. And nothing more. As what they claim on "defense related activity" is modeling of thermonuclear weapon. If so, as far as I understand, no ignition - no possibility of modeling. And ignition failed. That is a fact.kinkmode said:NIF closed? Once again I'm not quite sure what you are getting at. NIF might be facing a budget cut, but I'm sure the defense related activities of NIF are still being funded. Regardless...
With respect to HIF, apparently I need to eat crow. Here's what my friend wrote: The head of OFES killed the HIF program last month or so. LBNL and LLNL people working in HIF were either laid off or transferred back to LLNL. PPPL people are finding other things to work on now. In his eyes, with experimental program now gone and the elders no longer carrying the torch, no fresh blood will be entering research, so it will go the way of the US mirror program.
That being said, I saw the Senate approved a budget for HEDLP of $15 million, including HIF. So who knows.
Research idea where? In NIF?
NIF closed.

really?the_wolfman said:When you say NIF is dead, I wonder if you're thinking about NIC (the national ignition campaign). NIC was an experimental campaign on NIF with the purpose of igniting a target. NIC ended last year, and yes it failed to ignite a target.
Mr. kinkmode, without offence, how old are you? How many friend you have? And what percent of your fiend's community work on NIF? May be this is only natural wish of young man to look more significant than he is?kinkmode said:All my friends who work on NIF...
Joseph Chikva said:Mr. kinkmode, without offence, how old are you? How many friend you have? And what percent of your fiend's community work on NIF? May be this is only natural wish of young man to look more significant than he is?
2 OR 3?kinkmode said:I have 2 or 3 friends who work on NIF or related things.
And that is believable. As last year NIF failed to achieve ignition. And I do not believe that at facility making serious defense program anyone will allow to make movie. But they did that.kinkmode said:No, my friends didn't tell me NIF was working on fast ignition in the last year. I was speaking from memory from a conference I attended in 2008.
Heavy ion beam fusion involves accelerating heavy ions, such as deuterium or tritium, to high speeds using powerful particle accelerators. These ions are then directed towards a target containing a fusion fuel, causing a high-energy collision that results in the fusion of the ions and the release of large amounts of energy.
Heavy ion beams have a higher energy density compared to other fusion methods, making them more efficient at producing fusion reactions. They also have the potential to achieve higher temperatures and pressures, which are necessary for sustaining fusion reactions.
There has been significant progress in heavy ion beam fusion research, with several experiments successfully demonstrating fusion reactions using this method. However, there are still challenges to overcome, such as controlling the beam and target parameters to achieve sustained fusion reactions.
If heavy ion beam fusion can be successfully harnessed, it has the potential to provide a clean and virtually limitless source of energy. It could also be used for medical purposes, such as cancer treatment, and for powering space missions.
One of the main challenges facing heavy ion beam fusion is the high cost and complexity of building and operating the necessary particle accelerators. Additionally, controlling the beam and target parameters to achieve sustained fusion reactions is still a major hurdle that needs to be overcome.
