Maryna:
- only used signal MC for the CDR - now also doing bkg as well
- using energy depositions and divide by the mass of the sensitive volumes GeV—>Joule —> divide by mass to get Gy.
- new Boron(1%)+Polyethylene(50%)
- need to look at much higher signals
- all concrete should be Borated concrete? 

Tom:
- CDR assume 24 um RMS (80 fs)
- 10-20% increase of rates for smaller duration
- we now assume charge 0.25 nC and 16.6 fs
- will run also lower xi values.

Arka:
- 600 um will not stand the radiation
- go back to 35 um 
- Sasha is redoing the 35 um

Sasha:
- need new sim:
  - add the shielding behind the calo
  - also change to 35 um Bremss target 
- idea to have a permanent magnet upstream the Bremss shielding to remove high-E electrons:
   - need to check what happens first with he 35 um target and then decide
   - look at the high-E electrons at the detectors but also in the IP (dummy volumes)
