Status of the Merlin
Readout System
As it applies to the VELO Upgrade Testbeam
Richard Plackett - Detector Group
VELO Upgrade Meeting - 4/5/2012
Outline
•
Merlin – Medipix Readout with a LabView Interface
•
•
•
Developed as a precursor / development tool for EXCALIBUR system
Seems to have significant value in its own right
Versatile, high speed readout system for Medipix3
•
Developed mainly by Ian Horswell at Diamond
•
Will be delivered as a detector system to B16 and I16 beamlines this month
•
Looking at feasibility of making it more widely available, possibly through
Quantum Detectors

Current Medipix Features Supported
•
•
•
•
•
•
•
•
•
Single Pixel Mode 12 bit – counter zero
Single Pixel mode 24 bit – both counters
Test Pulses – arbitrary test maps
Digital Test – read to and write from both counters
DAC Scan / Threshold Scan
FBK Tracking (to fix temperature variations of MPX3.0)
Compatible with Pixelman pixel and DAC config files
Internal HV bias generated and software controlled
Trigger out signal available
• Many features close to working but need adding to control panel and
testing… please make requests

For the Testbeam…
Results of Discussions with Daniel and Jaap yesterday
•
•
•
•
•
•
•
•
Change local file saving to make time stamped folders optional
Ensure files are closed immediately after being written
Test PXIe build being prepared for VELO upgrade system
Test for 100fps for 20,000 single frame files into a folder (done)
Test triggering with beam structure (no problems expected)
Look at extending trigger out to include readout time
Send adapter card to arrive at CERN before 15th May
Diamond people able to remote desktop in to system at CERN to
help debugging if necessary.

Future…
• Soon
–
–
–
–
New adapter boards to be integrated
Support all Medipix3 modes and features
Add native Equalisation functions
Tidy up front panel etc
• Near
–
–
–
–
Support Medipix3.RX
More inbuilt automatic self test functions
More inbuilt analysis tools – histograms etc
Investigating making system more widely available
• Further
– Quad Support at 1000fps
– Multiple FPGA cards per system

Summary
• Merlin readout system for Medipix3 based on NI hardware
• Virtex5 FPGA running in a PXI(e) chassis with host
•
•
•
•
•
1000 fps burst and 100 fps continuous
Up to 10m VHDCI cable
Triggering with 10ns accuracy
Baseline Medipix3 functionality currently supported
Tested in Diamond testbeam and in Lab.
• Making some small modifications to run in VELO Upgrade testbeam
• Will perform specific tests with new build for PXIe system
• Adapter card and power card to arrive before 15th May
