Current Telescope

Strengths• High resolution (~2.5um)• Adaptability• Ease of use – Currently

borrowed by SPS collimator group

Weaknesses• Small number of Timepix

assemblies available• Scattering from PCB mount• Low readout rate (1Hz)• Large jitter on timing

(500ns)• Low rate for ToA

measurements

Future Timepix Telescope

New Readout

Timing Unit

DUT+ readout

New Readout

Timing Signals collected by a timing unit provide flexible software synchronisation

Telescope arms and timing unit read back to PC via Ethernet or USB 2.0

Target performance:75,000 tracks per second1um uncertainty at DUT1ns timing accuracyEven more convenient…

New ‘Single’ PCBs

Data IO – Backward compatibility with current chipboards

Serial IO – connecting boards as a ‘quad’ to be read out together

Sensor Bias – moved to a more convenient place

Sutter Output – An easy connector for monitoring and measuring the actual shutter signal

On board voltage regulators to ensure stable operation

Mounting Holes to accurately position chipboard

Cutout behind chip to reduce scattering

Chip positioning guides to ensure accurate mounting

New Readouts - RELAXD

• high REsolution Large Area X-ray Detector• Designed to tile large areas, currently PAN and NIKHEF flavors

due to parallel FPGA development

150MHz frame rate

70k tracks per second~15% active time

Prototype presented at latest Medipix collaboration meeting
