The study Valery and I did during g12 was done using the raw counts from the start counter PMTs to determine the current as best we could. I believe the pertinent figure is on page 14 (bottom). Showing the scalar rate vs beam current.<br>

I dug out the data from the beam intensity study which was done during the run. Performing a linear fit to the first few points shows that at 60 nA the MOR rate sags by about 8%.<br>
