Wanted: Tennelec Preamp

Before I make an eBay purchase, I wanted to see if anyone here has a charge-sensitive Tennelec preamp. It is the last part I need for my neutron detection rig.

Thanks,
Luke Harrill

Re: Somebody got quite a deal on eBay

I was bidding on it too, and like you, I regret not entering a higher maximum bid. The lucky bidder upped me by $5 before I could raise it more.

Fusor Progress, Luke Harrill

I've almost got all the parts for my vacuum chamber and gas system. (The missing parts are marked with index cards.) I also have a Welch 1402, a Televac TC gauge controller, 2 large 75k ohm power resistors, a variac, a 50kv probe w/ meter, and a rectified xrt w/ cables. I am still working on the fol...

Re: FAQ - Extensive paper on neutron activation

By "the physical book" I meant the book "Nuclides and Isotopes : Chart of the Nuclides 16th Edition" published by Knolls Atomic Power Laboratory.

Re: FAQ - Extensive paper on neutron activation

The IAEA currently has an android application entitled "Isotope Browser" It contains a chart of the nuclides, but I still find myself referencing the physical book more. Some here may find it helpful...

Re: Second Opinion on XRT

Thank you all for your input! I picked it up this morning for the grand total of $300! Since it was registered, he had a little paperwork to fill out for the N.C. Radiation Protection Section about its sale. So I might have to contact the S.C. DHEC and inform them of its correct "disposal/scrapping....

Second Opinion on XRT

I've finally found a transformer here locally, and I wouldn't mind a few opinions on it. Being from '91, it's not as old as I would like. It looks to be of considerable size though.

Re: Oil Diffusion Pump Questions

Andrew, Thank you for helping me identify this pump! Everything in the manual seems to be spot on. Dennis, My intentions were to remove it in hopes of finding the wattage. However, it is no longer necessary to do that since it is listed in the manual. On the other side of the coin, the replacement h...

Re: Oil Diffusion Pump Questions

The 3 copper pipes are this pump's equivalent of fins for cooling. A fan bolts on that piece behind the outlet, and forces air through the pipes to the holes in front. Unfortunately, removing the cartridge heater is one of the afore mentioned tasks that remain unaccomplished. I'm still unsure of the...
