Thanks for posting the talk (wow - that is really one deep UV "flash light": not a device to look into! I'd even be careful about any specular reflections from reflective surfaces. Is there anything the Chinese aren't making that isn't really off-the-wall? Some of the stuff just really strikes me as ...well, just couldn't for the life of me think why they'd make it and then you show how useful the items can be. Go figure.

Also, thanks for more of the HEAS photo's - is it possible to get some captions for ones that aren't obviously self explanatory and possibly names with some of the pic's of people?

Really have to attend the "sale" when I manage to go to the HEAS the next time it comes around (I've only been able to stay for one day each time I went previously and so missed out on the "Flea Market"! So many nice items (and not just fusion related.)

Susan, You really did a fabulous job of capturing images of the lab gear and the fleamarket. Thank you very much! I have captioned the photos. This was a great wad of photos.

For those who don't know, Susan has been to a few HEAS events and is currently in college going for her degree and nuclear physics. She asks questions to learn what methodologies are being applied.

Apparently Susan's camera date tag is stuck on May 25 2008

2017 HEAS will be remembered as the year of the vacuum goodies! We had four vacuum vendors and the competition was fierce! I spent close to $180 on vacuum materials, but near the end of the day, as the vendors packed up, Tim Koethe yelled out.."I do not want to take this stuff back"..... A small crowd ensued around his, still well stocked, vacuum gear table. I stayed the longest and packed several boxes that were sold at fire sale lot-in-a-box prices.

Dare I gloat.....Oh yes... and here are the images and data to prove it. Sorry for those who could not attend or for those who did and did not bring enough money to the table.

Look close at the KF 16 pile. (click on image) You will see a snap on-snap off bellows valve plus 2 micrometer metering valves.
Check out the feed thru image. One is a weldable HV BNC feed thru and the MDC 10 pin job is new in package... normal price on this is about $500.00

Opps.... I forgot the 6 Baratron capactitive 50 torr differential pressure manometer gauges with VCR fittings on one end of each. I will add the photo of them soon.

Just wow! I keep telling people about getting deals on fusor stuff and that it can be done but apparently, the best deals are at HEAS! Maybe next year I will remember this and be there as well!

That is really good and useful stuff, Richard!

LOL @ the Geiger ray gun.

I made recently a GM counter based on Arduino+LCD. It's mounted on a 4-foot long piece of wood (which I had previously used to test various compositions of wood varnishes) The GM tube is at one end of the stick with HV wires taped along the length of the wood. The Arduino, LCD and battery box are near the other end - the handle. I dub it my GeigerStik. It allows me to test stuff from a distance. :)
Unfortunately it's not rain-proof.
I plan to upgrade it at some point with a case for the Arduino+battery, and a HV connector at the tube end so I can change tubes easily.
There _is_ madness to my method.

You must be around some really hot stuff to need a GM on a stick!

I regularly handle some ore samples that are over 100,000 cpm as measured with a 2" mica windowed pancake tube....no problem, of course. After all, it is just NORM (Naturally Occuring Radioactive Material)....It's just rock! I picked these rocks up off the ground in the high desert of Utah.

As always, a smart person knows how to be safe. For protection I use the physics of the inverse square law, but when that isn't possible, (ore in my hand), I use the physics of tiny exposure times followed by inverse square law. I believe in hormesis, as well. Alas, I am never around enough radiation to let hormesis take effect.

Many, non-smoking miners in the poorly ventilated U mines of the 1950's lived to a ripe old age. It is mostly the common American of that period, who mined and smoked 2-3 packs of old unfiltered cigarettes each day that suffered a shortened life span. This was not due to exposure to uranium ore's intense and continuous radiation bombarding them within the mine, but the radon daughters they sucked in with each puff of satisfying tobacco smoke, that took them out early. Death came early due to the ultimate chronic exposure to radon daughters while inhaling smoking debris from a tubular weed that they set on fire and happily dragged into there lungs on a continuous and perpetual basis. It was never the particulate radiation given off by the ore that took them out, it was continuous daily exposure to Radon daughters and the two packs of old "Lucky Strikes".

For those who never smoked, that is 40 cigarettes set on fire and inhaled per day! I never smoked or drank but have worked around folks all my life who had both vices.

As a 15-year old in the mid 1950's I remember my dad asking me: "Do you know what LSMFT means"? My answer was: "Lucky Strike Means Fine Tobacco"? Dad answered: "No, it means Lord, Save Me From Truman".

Nope just lazy, don't want to bend down to test stuff that's on the ground. :)

Like that 50lb bag of KCl that sits in a corner of my garage and I occasionally use as a check source. Though that's not its primary use.

It's amazing how many things one wants to check when one doesn't have to crouch or climb on a ladder to do it.
