"One added benefit is that if the bomb is hardwired to detonator and someone has his hands on the detonator he's going to get a real tingling sensation ;)" I can't imagine that they build in circuit breakers as part of the "build de rigeur" in "IED 101"

This is nothing, I have a much hotter idea on interrogations at Guantanamo which I have withheld for just this reason. If there is no public domain background then that answers my question, if there is PD then we should be able to discuss, if there is non-PD then I'll just shut up and go away, glad to know that someone's on it.

Looking over this subject last weekend link The field of explosively driven pulse power and high power microwave has gotten way beyond technology I am aware of. The conference in London costs too much to attend. I can be reached at jin_bottle@hotmail.co.uk. I'll stick to cooking aircraft parts for now. Good luck frying the VBIED and the T hanging off it - those who care.

"Good luck frying the VBIED and the T hanging off it - those who care. " it's an esoteric interest... I think there's quite a few who do care.. ;) "I'll stick to cooking aircraft parts for now." what are you cooking?

lightningtest WOW a *Peaceful* application pulse power technology! - keeps the fruit fresh! 6/20/2005 6:11:03 AM

The 2005 pulse power conference is totally public domain as far as I can tell (russians, chinese and US, EU represented) The technical specs of some fearful tech can be gleaned from stuff on the website. Just to show all this sci-fi stuff is not all about destroying human life (and smashing atoms together) more efficently whilst consuming ever more tax dollars. 7.5 MeV HIGH AVERAGE POWER LINEAR ACCELERATOR SYSTEM FOR FOOD IRRADIATION APPLICATIONS Carl Eichenberger, Dennis Palmer, Sik-Lam Wong, Greg Robison Titan Pulse Sciences Division San Leandro, CA 94577 USA Bruce Miller Consultant, Albuquerque, NM USA Daniel Shimer Consultant, Danville, CA USA In December 2004 the US Food and Drug Administration (FDA) approved the use of 7.5 MeV x-rays for irradiation of food products1. Titan Pulse Sciences Division is developing a new food irradiation facility design based on this ruling. The increased efficiency for treatment at 7.5 MeV (versus the previous maximum allowable x-ray energy of 5 MeV) will have a significant impact on processing rates and, therefore, reduce the per-package cost of irradiation. The irradiation system incorporates a 7.5 MeV electron linear accelerator (LINAC) that is capable of >100 kW average power. The LINAC is an RF standing waveguide structure based upon a 5 MeV accelerator2 in operation at a food processing facility in Vietnam. The LINAC is powered by a klystron tube tuned to 1300 MHz (L-Band). The electrical drive for the klystron is a solid state modulator that uses inductive energy store and solid-state opening switches to generate a repetitive pulse train. The system is designed to operate a minimum of 7000 hours per year. 1. Federal Register Vol. 69 No. 246 (December 23, 2004) 76844 2. R.B. Miller, et al., Nucl. Insr. And Meth. In Phys. Res.

"The 2005 pulse power conference is totally public domain as far as I can tell (russians, chinese and US, EU represented) " actually there are a number of countries that don't submit technologies to the private events anymore due to that very reason. the UK run events tend to be commercial events, and certainly from the ones I've attended they have been highly attractive to Chinese delegates. I know for a fact that some US companies do not attend those events anymore due to security concerns. As an example, the Australian events are restricted, and even authorised delegates are not allowed to take digital devices such as cameras and portable recorders onto the premises. SMI's events are notorious for being an "open house" Chinese delegates can be seen "happy snapping" the vendors models. (even though the critical technology are vague representations and facsimiles only) IMV there is far too much COTS gear that is dual use and it shouldn't be hilighted in the public domain.

EW3 is spot on - the jin seems to be a Marx gen which mean relativly low current and high voltage. The reason I say this is that LL Labs have developed a small volume (but not low mass) marx which idicates to me a ground forces application. Naval don't have as much of a volume limit (thought is is a factor). Air and space have a weight limit. AN IMPROVED ULTRA-COMPACT MARX GENERATOR David A. Goerz, Tony J. Ferriera, Jay B. Javedani, and Ron D. Speer Lawrence Livermore National Laboratory Livermore, California 94550 USA Lawrence Livermore National Laboratory has developed a family of ultra-compact Marx generators for a variety of special pulsed power applications. These systems incorporate low profile, low inductance capacitors and switches, high-energy-density ceramic materials, highelectrical- strength dielectric materials, optimally shaped parts, and integrated packaging techniques to achieve higher performance in comparatively smaller packages. In general, we are striving to operate near the intrinsic strength level of each selected material. The prototype device described in this paper is a 30-stage unit that stores 500 Joules at a nominal charge state of 100 kV per stage. At this operating level the ceramic capacitor material is stressed to 60 kV/cm and the plastic switch body material is stressed to 300 kV/cm. We have plans to extend the performance to even higher voltages and energies. Pressurized SF6 gas is used to insulate components, and careful attention must be given to details of the interfaces to avoid local field enhancements that can lead to surface flashover and electrical breakdown. During initial testing of first generation prototypes we experienced some elusive problems that limited performance. Field modeling and closer examination of critical areas revealed that field concentrations in spaces required for thermal expansion of dissimilar materials was causing gas breakdown and surface flashover around the edge of the switch body. We devised a new switch design to better manage the fields at the insulator-electrode interface and eliminate this surface flashover problem. Many other improvements have been incorporated into the most recent prototype, including custom built charging resistors and coupling capacitors that are able to withstand very high impulse voltage stresses, and custom electrical contacts that simplify assembly and improve reliability. This paper describes the design of the improved ultra-compact Marx generator and presents field modeling, circuit modeling, and experimental data demonstrating its performance.

where can one go to discuss this tech at an acceptable level and in a acceptable format. + who is the threat if the chinese and russians are already their taking pictures. Wasn't russia defeated by spending excessive amounts trying to match US R&D? If the newer threats facing us try to go high tech (like HPM) then they will be wasting their money and losing their focus (plus make it easier for us to infaltrate them). The whole black budget thing could become a subject for discussion, peer review is what makes science work. Public disemenation of results allows society to provide feed back to the scientists on what we need. IMHO some aspects of mil tech could have done with that feedback. Less than lethal weapons being a major example - just right for the bleeding librals to apply on their restive taxpayers.

"where can one go to discuss this tech at an acceptable level and in a acceptable format. + who is the threat if the chinese and russians are already their taking pictures." certainly my view and associated experience is that if you approach the right people (in your case MOD), if they see the merits of what you are trying to achieve, the you will get access to peers in tha technology. You'll be surprised at what may be happening outside of the public arena.

gf0012-aust - No backing for generator development aimed at this "market" forcoming from my managers. However we recently got our MoD contract renewed and pot of money available for additional tasks beyond those already assigned to us. I need to put a more concrete idea to the management. All of our present contacts in MoD DPA are either Air or WMD. gf0012-aust Perhaps you could arrange for a UK contact who engages in similar "Esoteric" past times to meet me? QinetiQ are now private (owned my Carlyle Group and UK gov) and a direct competitor to us in many areas..... so selling colaboration with them to management may be problematic....True MoD would be better. I prefer to meet on UK MoD site (perhaps in a bar?). Those once bona fides are checked I am sure people could come to our Lab if required. I used to attend Bletchley TA centre (mid 1990's), I was a young not very adept techie not a Operator. Perhaps we could meet there if it OK with the OC. Contact through jin_bottle@hotmail.co.uk. Once we make contact I propose we liase and exchange DPA funding authority contacts details before meeting to establish I am bona fide (and Vice Versa :>) + check with OC of 1 Sigs if required.
