1 Run 2 Upgrade of the ATLAS Minimum Bias Trigger Scintillators Rachel Hyneman, College of William & Mary Advisor: Antonio Sidoti, Instituto Nazionale di Fisica Nucleare 1

2 A Reminder… MBTS is a set of 12 scintillating plates on each side of the beam line Set up in concentric inner and outer rings, with 8 and 4 plates each respectively Electronics carry and process scintillator signal to Central Trigger Processor (CTP) Includes basic coincidence checks Set-up acts as a trigger with low kinematic requirements 2

3 MBTS Signal Path Scintillating Plate (MBTS Counter) PMT (via Optical Fiber) 3-in-1 Card (Pulse Shaping and Amplification) TileCal Patch Panel (TCPP) (Part of Tile Calorimeter Electronics) MBTS Adapter BoardAmplifier Constant Fraction Discriminator Higher Level Signal Processing 3

4 “To-Do List” Check-Offs Install new 3-in-1 Cards and Use different PMT’s Checked with direct injection of charge, then via laser pulse into PMT Side A inner ring – not completed yet! Install CFD’s CFD’s are in place Voltage thresholds and output pulse widths have been set to be uniform, but not yet optimized Determining the minimum pulse-separation for which CFD will fire on two separate pulses Check MBTS output connections to the CTP All channels are working! 4

5 Visuals of Results 5 Above: Sample trace from laser pulse testing Side A, drawer EBA08 Left: Sample trace from charge injection testing (same drawer) Some samples of scope traces

6 Still to Come Characterize CFD’s further Check minimum pulse separation using different pulse shapes, voltages and amplitude ratios Optimize CFD delay parameter (so far, ~32 ns appears to be optimal) Optimize output pulse width Optimize threshold for expected signal Analyze output from cosmic ray testing (taken from M4 ATLAS Integration Week) Need to learn TileMonitoring package in Athena Compare outputs from 4 available channels Each has different discriminator set-up 6

7 Visual of Cosmic Data 7 MBTS data in purple (L1_MBTS_2) Can see that MBTS is firing successfully Further analysis to be completed…
