Development of a TDC to equip a Liquid Xenon PET prototype
A Time to Digital Converter was designed (CMOS 0.35 $\mum) in order to be
used in Liquid Xenon PET prototype. The circuit proved to be able to work at
-120 degrees C, while showing a resolution of 250 ps. The circuit enables a low
readout dead time (<90 ns) and provides a fully synchronous digital interface
for easy data retrieval.Comment: 4 pages, submitted to IEEE Transactions on Nuclear Scienc
An integrated CMOS time-to-digital converter for coincidence detection in a liquid xenon PET prototype
A Time to Digital Converter was designed (CMOS 0.35 ÎĽm) to perform coincidence detection in a Liquid Xenon PET prototype. This circuit proved to be able to operate at 150 K, while showing a resolution better than 250 ps. The circuit enables a low readout dead time (<90 ns) and provides a fully synchronous digital interface for easy data retrieval
NIKEL: Electronics and data acquisition for kilopixels kinetic inductance camera
A prototype of digital frequency multiplexing electronics allowing the real
time monitoring of microwave kinetic inductance detector (MKIDs) arrays for
mm-wave astronomy has been developed. Thanks to the frequency multiplexing, it
can monitor simultaneously 400 pixels over a 500 MHz bandwidth and requires
only two coaxial cables for instrumenting such a large array. The chosen
solution and the performances achieved are presented in this paper.Comment: 21 pages, 14 figure
The ALICE EMCal L1 trigger first year of operation experience
The ALICE experiment at the LHC is equipped with an electromagnetic
calorimeter (EMCal) designed to enhance its capabilities for jet, photon and
electron measurement. In addition, the EMCal enables triggering on jets and
photons with a centrality dependent energy threshold. After its commissioning
in 2010, the EMCal Level 1 (L1) trigger was officially approved for physics
data taking in 2011. After describing the L1 hardware and trigger algorithms,
the commissioning and the first year of running experience, both in proton and
heavy ion beams, are reviewed. Additionally, the upgrades to the original L1
trigger design are detailed.Comment: Proceedings of TWEPP-12, Oxford. 10 pages, 9 figure
Level-1 jet trigger hardware for the ALICE electromagnetic calorimeter at LHC
The ALICE experiment at the LHC is equipped with an electromagnetic
calorimeter (EMCal) designed to enhance its capabilities for jet measurement.
In addition, the EMCal enables triggering on high energy jets. Based on the
previous development made for the Photon Spectrometer (PHOS) level-0 trigger, a
specific electronic upgrade was designed in order to allow fast triggering on
high energy jets (level-1). This development was made possible by using the
latest generation of FPGAs which can deal with the instantaneous incoming data
rate of 26 Gbit/s and process it in less than 4 {\mu}s.Comment: proceeding of TWEPP-10 at Aachen. 6 pages, 4 figure
