It is used to readout 64 channels multi-anode photomultipliers and supplies 64 trigger outputs and a multiplexed charge output. The second version of this ASIC was received during summer 2006. It has been thoroughly tested at LAL since. This paper presents the results obtained and shows that the performances were found in agreement with the main requirements.

The chosen detection technology is Low Gain Avalanche Detector (LGAD) silicon sensors that can provide an excellent timing resolution below 50 ps. The front-end read-out ASIC must exploit the large signal derivative and small noise provided by the sensor, while keeping low power consumption. This paper presents the results on the first prototype of a front-end ASIC, named ALTIROC0, which contains the analog stages (preamplifier and discriminator) of the readout chip. The ASIC was characterised both alone and as part of a module with a 2×2 LGAD array of 1.1×1.1 mm 2 pads bump-bonded to it. The various contributions of the electronics to the time resolution were investigated in test-bench measurements with a calibration setup. Both when the ASIC is alone or with a bump-bonded sensor, the jitter of the ASIC is better than 20 ps for an injected charge of 10 fC. The time walk effect, which arises from the different preamplifier response for various injected charges, can be corrected up to 10 ps using a Time Over Threshold measurement. The combined performance of the ASIC and the LGAD sensor, which was measured during a beam test campaign in October 2018 with pions of 120 GeV energy at the CERN SPS, is around 40 ps for all measured modules. All tested modules show good efficiency and time resolution uniformity.

This instrument consists of a telescope made of two lenses and a complex electronic chain divided in two main sub-systems: the PDM (Photo Detector Module) and the DP (Data Processor). Each of them is made of several innovative elements developed and tested in a short time. This paper presents their performances before and during the flight

It is used to readout 64 channels multi anode photomultipliers and supplies 64 trigger outputs and a multiplexed charge. Since its delivery in November 2005, the MAROC chip has been tested at LAL. Despite a substrate coupling effect which affects the performance when all channels are used in high gain, the chip has shown nice global behavior and it has been used during beam tests at CERN in October 2006.

The TurLab laboratory, part of the Department of Physics of the University of Torino, is equipped with a rotating tank, normally used to perform fluidodynamics studies. In EUSO@Turlab project the facility is used to simulate different surface conditions with different optical characteristics, like snow, oceans, forests, glaciers, deserts, savannah in a very dark and rotating environment to test the response of JEM-EUSO's sensors and sensitivity. Moreover, it is possible to produce 'replica' of other types of luminous phenomena such as cosmic rays, meteors, city lights, lightnings etc. by using artificially controlled light sources. The detector is a simplified system consisting of a 25 pixel MultiAnode PhotoMultiplier Tube (MAPMT), a focusing lens and a read-out electronics using conventional modules. The experimental setup currently in operation has been used to check the potential of the TurLab laboratory for the above purposes and the acquired data are used to test the concept of JEM-EUSO's trigger system. In this paper we describe the EUSO@TurLab project, present examples of the luminous conditions produced so far, as well as the results of the tests of the JEM-EUSO first level trigger applied to the data taken at TurLab.

Its main roles are to correct the gain spread of MAPMT channels thanks to an individual variable gain preamplifier and to discriminate the input signals (from 50fC i.e 1/3 photo-electron) in order to produce 64 trigger outputs. A multiplexed analog charge output is also available with a dynamic range around 10 pe ( ~ 1.6 pC) and a 12 bit Wilkinson ADC is embedded. Three versions of this chip have been submitted. MAROC 2 is the production version for the ATLAS luminometer and MAROC3 is a version with lower dissipation and significant improvements concerning the charge (30 pe: ~ 5 pC) and trigger (discrimination from 10fC). This third version showed very good characteristics that are presented here.

It is designed for the appearance search o f $ oscillation in the parameter region indicated by Super Kamiokande, as the explanation of the atmospheric neutrino de cit. OPERA is a long baseline experiment, to be located in the Gran Sasso Laboratory in the NGS neutrino beam from the CERN SPS. The detector is based on a massive lead/emulsion target. Nuclear emulsions are exploited for the direct observation of the decay of the lepton, produced in charged current interactions. OPERA has a high discovery potential which is ultimately due to a very low background level and could therefore play a decisive role in the clari cation of the experimental scenario.

Even with large hemispherical photomultiplier tubes , the expected number of channels should reach hundreds of thousands. A funded R&D program to implement a solution is presented here. The very large surface of photodetection is segmented in macro pixels made of 16 hemispherical (12 inches) photomultiplier tubes connected to an autonomous front-end which works on a triggerless data acquisition mode. The expected data transmission rate is 5 Mb/s per cable, which can be achieved with existing techniques. This architecture allows to reduce considerably the cost and facilitate the industrialization.

It is composed by a MAPMT and a compact stack of three PCBs which deliver the high voltage, route and readout the output signals. The third board contains a FPGA and MAROC, a 64 channels ASIC which can correct the non uniformity of the MAPMT channels gain thanks to a variable gain preamplifier. Its main role is to shape and discriminate the input signals at 1/3 photo-electron and produce 64 trigger outputs. Laboratory tests performed on prototype and pre-series PMFs have showed performances in good agreement with the requirements.
