-12- Interface and Flexible Connectors RELAXD designed to read a Quad not 4 independent chips Need an interface and short flexible links Needs to be completed rapidly as potential problems with signal transmission need to be overcome CERN group will take this on as very coupled with the chipboard design. Interface Board Readout Board Power Regulator Flexible Couplings Timepix Chip Boards Overview Arms Chipboard RELAXD Interface Mechanics PMTs DUTs Timing Unit Pixelman Data Flow Modes

-13- ARM Mechanics Required to mount, protect and position four telescope planes Chipboards, RELAXD, Services and PMTs / Scintillators need to be integrated Chipboard mounting needs to be accurate Mounting to external hardware to be as universal as possible Needs to be relatively robust External alignment targets and references to chip position (clear plastic targets?) Needs to shade from light but not be ‘dark’ Overview Arms Chipboard RELAXD Interface Mechanics PMTs DUTs Timing Unit Pixelman Data Flow Modes

-14- Services (electronics etc for Arms) The Arm Mechanics need to support some services Cooling – fan cooling will require airflow, possibly temperature monitor and external port? Timing Signals – one or more timing signals from chipboards/interface routed to external port Trigger/shutter signals to RELAXD will require external ports Power supply 240V mains to 12V dc for RELAXD external power input port Ethernet – RELAXD ethernet may need to be rerouted to external port depending on design of mechanics Lots of small things heavily dependent on RELAXD and Mechanics Not all a strongly required but will make it into a nice package Overview Arms Chipboard RELAXD Interface Mechanics PMTs DUTs Timing Unit Pixelman Data Flow Modes

-15- PMTs + Scintillators Each arm ought to be capable of mounting a PM pair to provide fast timing and ‘triggers’ Will take HV from NIM crate and send standard PM signals back Coincidence area to be compatible with Telescope Active area Relatively little work as mostly off the shelf parts Consider making separate mechanics add-on for arms Coupled to mechanics and timing unit (to some level) Overview Arms Chipboard RELAXD Interface Mechanics PMTs DUTs Timing Unit Pixelman Data Flow Modes

-16- DUT Issues Will require a stage system similar to the current one to rotate and align DUTs Some programming work needed on current system to make it safe to use with various mechanics Mechanics development for new sensors and chipboards Integrating readout for Timepix/Medipix3 based DUTs easy with 3 rd RELAXD board, Beetle based devices will be harder and will make heavy use of timing unit for synchronisation Cold box for irradiated DUTs and integration with arms… Multiple DUTs for fast changeovers as we hope to be running ~100 times faster than last summer… Overview Arms Chipboard RELAXD Interface Mechanics PMTs DUTs Timing Unit Pixelman Data Flow Modes

-17- Timing Unit FPGA Board Looks possible with FPGA Development board Already purchased Stratix2 with Nios2 embedded processor architecture to drive IP link Need to provide accurate timing information 20ns quite easy, 1ns possible Better than 1ns needs to drive CERN Nino chip (future) Ethernet Readout Eventually will drive shutter signals to control system remotely from pixelman Probably 3 months work to get to working system Overview Arms Chipboard RELAXD Interface Mechanics PMTs DUTs Timing Unit Pixelman Data Flow Modes

-18- Timing Unit Software Some simple software required to save data received from timing unit for basic operation More advanced software to control modes of system easily should probably be integrated to Pixelman as a plugin Need to define modes of operation early to ease development...

-19- Pixelman Update Pixelman is being updated by Medipix group to better handle multiple chips Display – docking multiple previews and controls Operating system compatibility – Windows, Mac, Linux Data File Structure – fewer files for each run Moving to RELAXD is also a benefit as only 2 systems to start Some specific Testbeam Plug-in would be helpful but not essential Work is well underway now and is being finalised and tested Overview Arms Chipboard RELAXD Interface Mechanics PMTs DUTs Timing Unit Pixelman Data Flow Modes

-20- Programmable Switch or PC ? It would be beneficial to only run one ethernet cable back to the readout PC in the barracks RELAXD and Timing Unit will probably require a programmable gigabit switch to send data as ethernet protocols are not very advanced Programmable switches like this can be purchased off the shelf but we need to investigate more to ensure this solution would work Would it be better to just have a PC with 4 Ethernet cards in the area as before?

-21- Question? - Operational Modes There are a number of ways we could run the timing unit, we can process scintillator coincidence data in real time We can drive the shutters with a signal generated by the FPGA We can suppress data outside beam spill We can run for a predetermined number of triggers and close the shutter We can run a burst of triggers and then wait We can run with an external shutter We can program delays and set modes remotely These options give a large number of permutations which need to be discussed What do we want to do with the system? Overview Arms Chipboard RELAXD Interface Mechanics PMTs DUTs Timing Unit Pixelman Data Flow Modes

-22-Conclusions There is still a lot to do Many tasks are decoupled from one another Getting the full thing for April will be very hard work At all times we will always have what we had before (and more) We cant go backwards Delivering any of the decoupled systems brings a benefit to the quality of the system and the data.
