[Sneap] looking for proton facility

[Roberts, Andrew D]

We don't have the full range, but could handle up to 400keV.  Maybe someone else has a higher energy machine available?

Subject: [Sneap] looking for proton facility

My company is building an electron and proton detector for an Air Force satellite. We need a low energy proton source for calibration. The instrument detects over an energy range of 30-2000 keV. We would like to calibrate over as much of this range as possible. Our maximum count rate is 2x10^5 particles per second.   The total envelope of the instrument and vacuum compatible rotation stage is 9 x 8 x 9 inches. In space the instrument can differentiate between particles coming in from different angles. To calibrate using a fixed beam, we plan to rotate the instrument in relation to the beam.

We will be calibrating using an electron source at NIST in Gaithersburg, MD. We are also building a higher energy range instrument that we have calibrated at the Massachusetts General Hospital Proton Therapy Center, but they are not able to provide the low energy protons for this instrument.

Any leads on a facility with an external use program that has a proton source that we could use for this calibration would be greatly appreciated.

I have already contacted all the US facilities on the ELSA website, and they are either higher energy or no longer available.  My apologies for anyone on the U of Albany SNEAP forum that is see a duplicate request.

Thank you,
