As some of you, well, maybe most of you know, (and I am only repeating this for the ones that might not, so sorry if I am repeating myself here), ...where was I?..Oh yeah...I started working in the Particle physics lab at Cornell, doing R and D type stuff..mostly design and detailing of their projects, and CAD management stuff...

Anyway, On the other site I started posting different things I have been doing, and decided to start a thread about it here..Some have expressed interest in the things I am involved in, while others yawn, and still more scratch their head, and say "huh?'...

Anyway, heres a recent article about some stuff we are doing.
These are the parts of Cornell's efforts to build a new linear accelerator, and use as a test bed for future upgrades at CERN, and other accelerator projects around the world.

Electron accelerator scientists report breakthroughs

By Anne Ju
Cornell scientists have surpassed two major scientific milestones toward proving the technology of a novel, exceedingly powerful X-ray source.

For more than a decade, Cornell scientists have been conducting research and development for an Energy Recovery Linac (ERL) electron accelerator that would produce X-ray beams 1,000 times brighter than any in existence.

The university ultimately hopes to use ERL technology to upgrade the Cornell High Energy Synchrotron Source (CHESS), one of five U.S. national facilities for hard X-ray synchrotron radiation research.

The National Science Foundation provided $50 million for 2006-14 to build instrumentation for prototyping and testing ERL concepts proposed by the Cornell team of faculty, students and collaborators. Specifically, the program goals are to prove that electron beams of unmatched quality could be created and accelerated to continuously produce X-ray beams with the laserlike property of coherence. No such X-ray source presently exists.

Cornell's ERL team is now reporting that its prototype electron injector is producing beams with a so-called emittance of 0.8 micrometers -- the smallest ever recorded from an electron source of this type. The injector is the key component needed to make an ERL work by creating electron beams that are tightly packed and traveling at nearly the speed of light. The emittance is a measure of how tightly packed the electron beams are.

This small emittance, say the scientists, proves that the ERL could produce X-ray beams focused down to exceedingly small volumes, allowing investigation of materials with unprecedented precision and speed.

In another breakthrough for the ERL project, the scientists have built and tested a prototype seven-cell superconducting radio frequency (SRF) cavity. SRF cavities are needed to accelerate the electrons from the injector to very high energies in order to produce the X-rays. The SRF cavities are operated at -456 F (-271 C), just 2 degrees above absolute zero temperature.

The Cornell researchers' SRF cavity has met the first performance specifications necessary to continuously power a high intensity ERL. It has been tested in a vertical cryostat at the required temperature and electric field gradients -- a significant milestone because it proves the cavities can perform at high power while within the scientific and cost parameters of the project.

The team must now demonstrate the efficacy of their cavities in horizontal tests, which will take place in 2012.

"These developments go a long way toward proving that an ERL X-ray source will work as predicted by simulations and theory," said Sol Gruner, director of CHESS.

This is so exciting! Thank you for sharing

How in the heck are you doing !!! Good to see you

Silverback · 10-29-2011, 05:34 PM

I'm just amazed when I think back what you were going through a few years ago.

Way to fucking fight and come out on top.

**TheSickness** · 10-29-2011, 05:39 PM

You are still a shitty driver

Howya doin

Thanks,,
Im doing pretty well..lots going on...I am also designing a 145,000 sq ft pharmaceutical plant for the company in PA that fired me 4 yrs ago..They bought a new building and asked me to design the new plant for them..

How are you guys doing?..Good to see you too..

Thanks John..I couldnt have made it through all that shit without you guys being there to listen to me whine..No horseshit..as Timmy D would say..

Eh it's still attached

Ya Fuckin Fuck

Got Joey Mags over here now.....He said you're move to NY saved your Pennsyltucky lovin ass too

**Riff** · 10-29-2011, 05:47 PM

lol...yeah..in more ways than one actually...Still feels like Pennsyltucky here though..
Ithaca is 10 sq miles surrounded by reality...I like it...hehe

Miss you a great deal Bro...Wish you posted up more here though

**ViperJeff** · 10-29-2011, 05:53 PM

All I can say is WOW....

Proof positive the power of the collective prayer works. I'm happy each time you post with what going on and the success's your having

This thread I will look forward too

Jeff

I will..I have alot going on, and even though I dont have alot to say, for fear of sounding like a dork, I still read alot of whats going on..trying to keep up is difficult with you guys though..lol..

I might be doing some traveling in the Spring, so we will see where things take me..you never know when I might drop in for a visit...

**ViperJeff** · 10-29-2011, 05:54 PM

Now that would be cool
