[Sneap] looking for proton facility

[Joy Stafford-Evans]

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,
