From: Sally Seidel Sent: 15 August 2011 20:31 To: Michael Moll Subject: proton irradiations in New Mexico hi Michael, I'm writing to ask you to add some information to the RD50 Irradiation Facilities page, regarding New Mexico. New Mexico can provide 800 MeV protons as well as neutrons and gammas. Protons are available at no monetary cost through the LANSCE facility at Los Alamos. The UNM group submits a proposal annually to LANSCE in March, requesting 2 irradiations per year (typically June and December) in the 800 MeV beam. The proposal is peer-reviewed. Thus far all of these proposals have succeeded. We typically ask for 48 hours (which corresponds to approximately 10^16 when accelerator inefficiencies are considered) in each of the two runs, however if higher fluence is required by an RD50 collaborator, we can request it, as long as we know this before March 1 of that year. Some information about the irradiation runs was provided by Jessica Metcalfe on page 5 of her talk at the 14th RD50 Workshop. That is: The hardness factor is 0.71. There are 5 x 10^11 protons per pulse at 1 Hz. The beam spot has approximately 2 cm diameter. We store the devices in a freezer immediately following their irradiation. Los Alamos and UNM handle dosimetry and shipping. We staff the shifts but welcome RD50 collaborators to join us if they wish. kind regards, Sally
