0. Motivation 0.1 Beam Secondary shower acquisition system upgrade. Current System: Need to set-up working point of PMT gain & Filter selection Working point has an impact on Beam sigma measurements (PMT Saturation) Limited dynamic range in any configuration (Tails measurements) High Intensity beams rise up noise level. Upgraded System: New detector: pCVD Diamond detectors Tunnel acquisitions and digital data transmission GBT protocol: Avoid long coax cabling High dynamic range (1e6) no tuneable parameters : Several channels on parallel or Logarithmic acquisitions BE-BI-BL Jose Luis Sirvent Blasco (jsirvent@cern.ch) 3 Scintillator Filters PMT Preamplifiers

2. Measurements 2.1 First Losses detected on the tree systems BE-BI-BL Jose Luis Sirvent Blasco (jsirvent@cern.ch) 8 Observations: 1. Signals from the pCVD diamond detectors show very fast single losses 2. Detector size seems to be important for losses detection (random nature) 3. Top detector is showing a lower amplitude for some reason (same set-up) 4. Losses correlation with PMT only on very high losses.

BE-BI-BL Jose Luis Sirvent Blasco (jsirvent@cern.ch) 12 3.Measurement Campaign #1 : 2015_10_09 (Summary) LHC_Pilot/MD2 1e11PpB @ 26GeV MorningNight (Beam dynamics changed profile width) Datasets: 4 Beam profiles in each dataset, All signals taken with LeCroy Scope, Allways considering 1m/s, In & Out scans are mixed on these measurements (different speeds not considered). Conclusions: 1.Beam size calculated with both systems and beam sigma STD are comparable Clear from the Gaussian goodness-of-fit that for these beam conditions PMT and SCINT shows better performance. Very spicky profiles with diamond detectors: Detector effective area 1cm2 (pCVDs) VS 300cm2 (Scintillator) Particles distributed randomly in the shower cone Possibility of detecting with higher efficiency neutrons on pCVD diamonds than on Scintillator (to be checked) 2.Improvement shown when combining the diamonds measurements, but far from SCINT performance in goodness-of-fit.

BE-BI-BL Jose Luis Sirvent Blasco (jsirvent@cern.ch) 23 4. Measurements Campaign #2: 4.1 Summary *Acknowledgements to E. Piselli and B. Dehning for his support and help during the measurements. Beam Intensity and Beam Energy influence on pCVD diamond detectors performance for beam profile monitoring. Diamonds on Surface VS QIE10 : better results obtained with QIE10 front-end in terms of noise and GOF. Need to optimize detectors placement based on Simulations for 26Gev and low intensity monitoring. For 1e11 PpB diamonds show comparable performance with the PMT + Scintillator system
