Anyone know whre to buy laser diodes that are 1 nm-100nm?

The Alcator is shut down. It is located where I will be working in Boston, I'm removing the 4 megawatt Klystron RF power amplifiers from that system and reinstalling them in San Diego on another Tokamak I will work on next year.

Interesting new work and job--best of luck with it. Very advanced and expensive effort. Cool!

There was some talk about upgrading the General Atomics San Diego facility for higher powers or maybe building a bigger tokamak earlier this year as at GA they were able to get some encouraging results by flipping the the orientation of the plasma chamber of an older machine from "D" to "L" --they achieved some surprisingly high pressure ramped up enough to meet the requirements for fusion power reactions to occur, with energy levels much higher than expected.
A bigger scaled up machine might do the trick.
"The planned year-long activity will enhance DIII-D systems by adding increased and redirected particle beams and radio frequency systems to drive current and sustain the plasma in a so-called “steady state.” The improvements will also expand capabilities with the installation of new microwave systems to explore burning-plasma-like conditions with high electron temperatures. This will allow researchers to explore how to achieve higher pressure and temperatures while increasing control of the plasma, conditions critical to sustained fusion operation." From:

Yep, that’s what I’m hired to help with, the RF current drive MIT is providing. Department of Energy has given MIT a grant to work on that with GA. My position being funded by them.

Enjoy it---will be something different and at one of the real world cutting edges of a combined domestic and international fusion energy effort.
Those sort of jobs where you have one foot in the here and now and one foot in the future are few and far between.

I wanted that job more than any other and turned it down a few months ago due to having it so good in my current job with high pay, a company paid for apartment and car (but boring work), then they came back to me yesterday asking if I would reconsider, so I did and said OK, how soon? Ever since I turned that job down I keep seeing MIT this and MIT that, kept thinking about the one that got away by my own choice, I wasn't happy with it. I'm a 9th grade high school drop-out (although I went to college later and received an AAS). Considering how little education I have, working for MIT is the most awesome opportunity I've had yet. I'm not going to be part of staff, it's separate from the full fledged employees, but just working with them is good enough for me.

Fusion is the power of the future....and may always be. I hope it works but not holding breath.

Me either, but the temperatures have been increasing at a Moore's law rate, they will achieve it.

That's plenty Four Yagi's is more fun than 16, because you don't have to work your back side off building it, and then keeping it working. When I first became interested in EME I had a lot of fun with two 17 element 144 MHz Yagi antennas for moonbounce, of course I couldn't work anyone unless they were a big gun, but the ratio of fun to work was high.

Here's a photo of my new toy:



I will start working on it in August.

You are going for that job now after all Chris? Excellent.

Edit: I'm very happy for you. What an amazing opportunity that awaits you.

Yes, it' a sweet and sour situation, sweet to go there and work with real science, sad to leave my high paying job behind, but money isn't everything and the job pays enough there. I'm surprised they have come back to me a second time after I turned it down, seems they couldn't find the right fit, or someone who was willing to split their time working in both Boston and San Diego. I will find out more later why they were this gracious to give me a second shot. Maybe it wasn't so much grace as need due to the applicants they were getting, or perhaps not getting.

That is rare for a company to come back for a second job offer. Especially these day. Best of luck.

New adventure, I just couldn't think about MIT without feeling sad I didn't take it the last time. I wouldn't have reached out a second time myself, if I were them.

Well consider yourself very fortunate. And I'm sure you will enjoy this job a lot. You'll be around some very talented individuals too.

Love to see a video tour if you are allowed

I thought you had taken that job before now, Chris. I could have sworn you told me that earlier than now. If not, congratulations.

I did accept, then like a bone head, turned it down due to personal challenges making the transition appear unworkable, but it wasn't, those now solved. A few months went by, they advertised the position again, but couldn't find someone they wanted to hire for the job, so reached out to me again. I am still waiting for official HR approval the second time around. Not sure if there will be a red tape issue to accept me back or not, waiting. They may need to re-advertise it for me to apply once more to get this done.

Yikes! I had no idea. Live and learn.
