  1. Results from PHY3 Testsin DESY, Zeuthen H. Henschel H. Henschel – FE Electronics

  2. PHY3 Tests in Zeuthen Aim - prepare a frontend test setup with powering sequencer test pulse charge injection readout ADC and data logging - evaluate the PHY3 prototype chip dynamic range linearity timing (peaking times & readout) H. Henschel - FE Electronics

  3. PHY3 Tests in Zeuthen Readout board for PHY3 chip with - control input/output - level shifters - biasing switches & networks - power connector - 18 FE inputs - Amplifier H. Henschel - FE Electronics

  4. PHY3 Tests in Zeuthen Test Setup: - LabView driven I/O register - 2 Pulsers for HOLD signal & Charge injection - Oscilloscope for output evaluation H. Henschel - FE Electronics

  5. PHY3 Tests in Zeuthen Input Timing hold signal is shifted w.r.t. input pulse H. Henschel - FE Electronics

  6. PHY3 Tests in Zeuthen Serialized Output (so far slow clock rate <1kHz because software generated - hardware based sequencer ordered…) H. Henschel - FE Electronics

  7. PHY3 Tests in Zeuthen PreAmp linear range measured on Channel #0 direct output H. Henschel - FE Electronics

  8. PHY3 Tests in Zeuthen Sequential Readout • definite charge of 0.33pC injected into one channel after the other • readout with (slow) clock, hence considerable decay of captured charge is observed H. Henschel - FE Electronics

  9. PHY3 Tests in Zeuthen Achievements - basic frontend test setup with powering sequencer (slow, software based) test pulse charge injection (manually switched) readout (to scope so far) ADC and data logging (not yet accomplished) - evaluate the PHY3 prototype chip dynamic range (gain 10 only / gain 1 branch not working?) linearity (preliminary results) timing (fast readout to be investigated) H. Henschel - FE Electronics

  10. PHY3 Tests in Zeuthen Outlook • complete measurements with PHY3 chip, use with real detector samples • operate dynamic Gain1/Gain10 switch • purchase flexible and fast sequencer, prepare a versatile program • continue with subsequent prototypes …(?) Measurements & Advice: Thanks to A. Ignatenko, W. Lange, C. de la Taille! H. Henschel - FE Electronics
