1. News Request to install SLAC collimator in SPS
Request to install UA9 equipment in SPS
Request to install new wire scanner equipment
Talks at HiLumi (HL-LHC impedance model and crab cavities impedance in SPS)
PSB impedance model
Model for elliptical transition is converging
Proposal to reduce impedance in the SPS (flanges, kickers)
Many impedance measurements
CST 2014 can not import anymore the CATIA models from SMARTEAM, need to wait for 2015
BSRT measurements
TDI work ongoing for the spare and the HL-LHC ones

2. SLAC collimator for SPS

3. SLAC collimator Need to check open geometry only (+/- 30 mm)
Tank in stainless steel and jaws in copper
Geometry regenerated from simplified model sent by SLAC
One

4. Longitudinal impedance
 Many modes!
Effective longitudinal impedance im(Z/n)~20/(0.6e9/44e3)=1.5 mOhm
Not significant (for SPS)

5. Effective geometric transverse impedance for 5 mm displacement:
2.4 kOhm/m in H
2 kOhm/m in V
Not significant for SPS.

6. Shunt impedance (LinacOhm) vs frequency
 Small shunt impedance for modes expected (max 600 Ohm at 1.45 GHz)

7. So far no show stopper expected.
