  Thus far the following people have expressed interest in a participation and I have tentatively suggested tasks. Illinois will also try to get a good undergrad involved in this work for a Senior Research Thesis.

 We plan to use the following detectors
  • Entrance beam counters muPC and muSC available from MuCap experiment
  • target detector for BG measurement, use Si strip from Hogan, this is also a backup for MSX25

  • near detector, purchase or Si strip or none? MSX25 are made a thin as 20 um.

  • pfDet purchase from Micron
  • Illinois will build a muVeto counter and a thicker plastic counter for high energy protons.

 MuCap/MuSun/MuLan has a working DAQ system for chamber readout and FADC recording of scint/Si pulses. We also have preamps probably suited for the Si detectors. We will help to get the electronics started, but support during the run is required (Vadim,...).

If I use C/A ~ 1 [pF/cm] 1/w, w being the depletion width, we get

  So perhaps a 30x30 mm2 detector MSX09 is preferable, if the rate is ok.

Neutron detection

We have liquid scintillation neutron detectors, capable of neutron-gamma discrimination. Does Los Alamos have calibrated neutron detectors and would be interested in unfolding the measured spectra?

DIO

Changed:
<
<
Interest in measuring DIO was expressed, but it is not clear to me that the required instrumentation and expected statistics make such an effort worthwhile.

Vadim with Peter's help will perform a GEANT4 study of the experiment, with the main objectives:
  • Concept ok? Count rates?
  • Uncertainties in reconstructing the primary capture spectra from measured distributions. Optimization of Si detector size. Do we need near counter? Do we need He or vacuum, I hope not.
  • Basic hardware arrangement, do we need vacuum feedthrougths etc

We plan to use the following detectors

  • Entrance beam counters muPC and muSC available from MuCap experiment
  • target detector for BG measurement, use Si strip from Hogan, this is also a backup for MSX25
  • near detector, purchase or Si strip or none? MSX25 are made a thin as 20 um.
  • pfDet purchase from Micron: I would get one Stock B4 MSX25-1500 # $2,000, which is a discount offer. I hope we can get a second one.
  • Illinois will build a muVeto counter and a thicker plastic counter for high energy protons.

Gamma detection

The idea is to measure the gamma spectra from RMC and radiative pion capture. Jim do you have a large NaI available? Let's estimate the rates.

Neutron detection

We have liquid scintillation neutron detectors, capable of neutron-gamma discrimination. Does Los Alamos have calibrated neutron detectors and would be interested in unfolding the measured spectra?

DIO

Interest in measuring DIO was expressed, but it is not clear to me that the required instrumentation and expected statistics make such an effort worthwhile.

Electronics

MuCap/MuSun/MuLan has a working DAQ system for chamber readout and FADC recording of scint/Si pulses. We also have preamps probably suited for the Si detectors. We will help to get the electronics started, but support during the run is required (Vadim,...).

If I use C/A ~ 1 [pF/cm] 1/w, w being the depletion width, we get

w(cm) C/A=1pF/w A C
0.01 100.00 pF 1.00 100.00
0.15 6.67 pF 25.00 166.67
0.15 6.67 pF 9.00 60.00

So perhaps a 30x30 mm2 detector MSX09 is preferable, if the rate is ok.
