  1. Screen printing MM test,current status and plans Atsuhiko Ochi Kobe University 6, November 2012 ATLAS MicroMEGAS meeting

  2. Status of chamber preparation • Screen printing – MM has already been assembled with gas package. • Readout : 1-Dimensional, 400um pitch • Gas gap : ~ 100 um (estimated) • Drift length : ~ 1cm • Operation test • Gas: Ar:C2H6 (7:3) • Signal of beta source (90Sr) were observed • No HV current found (<10nA) • At first, in the burn-in stage, we found steady current of a few micro ampere. • Estimated gain … a few thousand • Vstrip = +520V, Vdrift = -1kV • We need to reduce the nise.

  3. Test plan at CERN • Site of the test • H6 test bench, using parasite beam • Schedule • Because of administration work, we will be ready to enter the test beam site from 14th November. • We will check position/timing resolution for various voltages of strips and drift plane. • We will take a data for comparing to existing MMs. • Estimated test term is one week • Maximum, 2 weeks. • Ochi and Edo will join from Kobe. • We need helps from test beam experts. • Materials to be need • Readout: Two APV25 cards and their readout system • HV supplies (Positive and Negative) • Gas system A.
