“…In order to reduce the space occupied by the PMT base, as well as its cost and power consumption, two application-specific integrated circuits (ASICs) have been developed. 27 As the DOM is tightly packed with the 31 PMTs and the electronics, compactification is crucial. The first ASIC is the so-called PROMiS ASIC, which performs the readout of the PMT signals and has two different parts, one digital and one analog.…”

Sebastiano Aiello et al., "KM3NeT front-end and readout electronics system: hardware, firmware, and software,"Abstract. The KM3NeT research infrastructure being built at the bottom of the Mediterranean Sea will host water-Cherenkov telescopes for the detection of cosmic neutrinos. The neutrino telescopes will consist of large volume three-dimensional grids of optical modules to detect the Cherenkov light from charged particles produced by neutrino-induced interactions. Each optical module houses 31 3-in. photomultiplier tubes, instrumentation for calibration of the photomultiplier signal and positioning of the optical module, and all associated electronics boards. By design, the total electrical power consumption of an optical module has been capped at seven Watts. We present an overview of the front-end and readout electronics system inside the optical module, which has been designed for a 1-ns synchronization between the clocks of all optical modules in the grid during a life time of at least 20 years.

“…The PMTs are equipped with a compact active base [9] which serves to feed the PMTs with high-voltage (of order 1 kV) and to process the PMT signal. High voltage is generated directly on the base by a Cockroft-Walton circuit which is controlled by a application-specific integrated circuit (ASIC) named CoCo [10]. Pulses from the PMT are translated to a time-stamp and the duration that the signal is above a configurable threshold (equivalent to 0.3 photo-electrons).…”

The KM3NeT collaboration is currently constructing the first phase of a cubic kilometer-scale neutrino detector in the Mediterranean Sea. The basic detection element, the Digital Optical Module (DOM), houses 31 three-inch photomultiplier tubes (PMTs) inside a 432 mm glass sphere. This multi-PMT concept increases the photocathode area by a factor of three compared to a design with a single 10 inch PMT, leading to a significant cost reduction. Moreover, this concept allows for an accurate measurement of the light intensity (photon counting) and offers directional information with an almost isotropic field of view. We will discuss these aspects and the enabling technologies, which include 3D-printed PMT support structures, and custom low-powered PMT bases, which provide the HV and digitization of the analog signal. An FPGA-based readout system transfers all sub-nanosecond timestamped photon signals to shore via optical fibres. The DOM design has been validated and its physics potential has been proven in the operation of prototypes deployed in the French and Italian detector sites at 2500 m and 3500 m depth respectively.
