Greg's Trade List
To acquire
If you would be willing to lend or donate any of the following items, or can offer a good (i.e. really low) price or a reasonable trade, please let me know as soon as possible.
- "Bubble"-type neutron dosimeter – I don't know who in their right mind would throw one away, but it can't hurt to ask...
- Gaskets (copper or Viton) to fit ConFlat-type UHV flanges (for 2.75", 4.5" and 8" flange ODs)
- Mains step-up transformer (115V to 230V), ~700VA or greater capacity
- MHV/BNC connectors: cable, panel-mount, etc.
- Coaxial cable rated for at least 2000V
- Aluminum "T-slot" beams and hardware
- Tungsten or molybdenum wire, somewhere around 1mm-2mm in diameter, at least a ~25cm length
- Flexible single-conductor wire/cable with insulation rated for at least 40kVDC
- Neutron, X-ray and/or gamma detector devices – I already have a boron trifluoride neutron detector tube, but I could use a more sensitive neutron detector, more GM tubes for x-ray safety monitoring, and/or a proportional gamma detector for gamma spectroscopy experiments...
- Lead sheet, ingots, shot, etc. for x-ray shielding. The sheet form is most convenient, of course.
- Aluminum or 304/316 stainless steel tubing, plate, etc. There's no such thing as too much scrap.
- "Webcam"-type camera(s), pref. at least 640x480 resolution and good sensitivity
Of course, if you have items to get rid of which are not on this list, I still may have a use for them...
