1 Advanced Implantation Detector Array (AIDA): Update & Issues Tom Davinson School of Physics & Astronomy The University of Edinburgh presented by Tom Davinson on behalf of the AIDA collaboration (Edinburgh – Liverpool – STFC DL & RAL)

2 Prototype AIDA ASIC: Channel Layout High (20MeV FSR), intermediate (1GeV FSR) and low gain (20GeV FSR) channels in parallel Blocks are sequenced to follow signal’s flow (“left to right”) Shaper and peak hold at back end to minimize noise 400  m x 6mm 400  m ~6mm Preamplifiers + feedback 700pF feedback capacitor High speed buffer Fast comparators Slow comparator Shapers Peak Holds + MUX

3 Prototype AIDA ASIC: Top level design Analogue inputs left edge Control/outputs right edge Power/bias top and bottom Prototypes delivered May 2009 MPW run 100 dies delivered Functional tests at STFC RAL OK

4 Prototype AIDA ASIC: Analogue input and bias reference

5 Prototype AIDA ASIC: Analogue outputs

6 Prototype AIDA ASIC

7 1: Medium Energy (ME) + ME Input signals (voltage step capacitive-coupled) Preamp buffered output (Low-Medium Energy Channel) Trigger output “Data Ready” signal Variable medium-energy (ME) event followed after 5us by a second fixed ME event: the energy of the first event (11.75pC, 23.5pC, 35.25pC) does not affect the response to the second (11.75pC).

8 1: Medium Energy (ME) + ME Input signals (voltage step capacitive-coupled) Analog output (peak-hold multiplexed output) Trigger output “Data Ready” signal When the data ready signal is active, the correct value is present at the analogue output (after the hit has been detected and the correct address been fed into the output multiplexer). NB: the test environment is very noisy and that affects the measurements.

9 2: High Energy (HE) + ME Three high-energy (HE) events (610pC, 430pC, 250pC) followed by a ME event (28.8pC): the initial HE event does not affect the response to the second. [The roll-of of the L-ME channel preamplifier is due to the HE channel amplifier becoming active: the two are effectively in parallel. Note the Range signal changing status after the HE event] Input signals (voltage step capacitive-coupled) Preamp buffered output (Low-Medium Energy Channel) “Range” signal High = high-energy channel active “Data Ready” signal

10 2: High Energy (HE) + ME Analog output (peak-hold multiplexed output) “Data Ready” signal Although the low-medium energy channel preamp saturates, the correct value is stored and multiplexed to the Analog Output when the “Data Ready” signal is active. Preamp buffered output (Low-Medium Energy Channel)

11 3: High Energy (HE) + ME Fixed high-energy (HE) event (610pC) followed by three ME events (15pC, 30pC, 45pC): the ASIC recovers autonomously from the overload of the L-ME channel and the second event is read correctly. Input signals (voltage step capacitive-coupled) Preamp buffered output (Low-Medium Energy Channel) “Range” signal High = high-energy channel active “Data Ready” signal

12 3: High Energy (HE) + ME First value (constant) given by the High-Energy channel, second by the Medium-Energy channel. Input signals (voltage step capacitive-coupled) “Range” signal High = high-energy channel active “Data Ready” signal Analog output (peak-hold multiplexed output)
