Description | By | Status |
---|---|---|
Simulation of crystal interaction | Simon | Have some data in attached PDF |
We will need a magnet | Tim, Lau, Henric | We have use of the MNP17 magnet we can decide on location |
Sergio pointed out that the crystals have to be carefully aligned with respect to the beam. Therefore we need a suitable mechanical support | Markus, Simon | UJ will provide Labview controlled goniometer |
The team proposes to test the crystal with both positrons and electrons | Tim | Estimate if T9 provides enough of the particles at the right energy and if inefficiencies in the particle identification could be a problem |
The team proposes different materials that could be used for growing the crystal. Do we have a preference? | Tim, Sergio | Simon states the team will likely have one Diamond undulator and one Si-Ge |
Sergio mentioned that synchrotron radiation may cause a background that masks the x-rays from the crystal | Tim, Sergio | discuss this further |
What impact does the beam environment have pre- and post-crystal? Would a vacuum tube be feasible? | Tim | Looking at NA43/59 documentation |
