Abstract

The Timepix3 hybrid-pixel readout chip consists of a matrix made of $256\times256$ square-shaped pixels with a 55- $\mu \text{m}$ pitch, which can be hybridized to several semiconductors, such as silicon (Si) or cadmium telluride (CdTe) with thicknesses up to 5 mm. Working as an event-based readout chip, it simultaneously records the time-over-threshold (ToT) in each pixel, measuring the deposited energy, as well as the time-of-arrival (ToA), with a time resolution of 1.5 ns. In this article, we present the energy calibration of two Timepix3 chips: the first one was bump-bonded with a 300- $\mu \text{m}$ -thick silicon sensor and the second one with a 1-mm-thick CdTe sensor. Both detectors were calibrated with per pixel calibration, using the monochromatic SOurce of Low-Energy X-rays [SOLEX from Henri Becquerel National Laboratory (LNHB) at CEA Saclay] and a set of calibration-grade sealed radioactive sources. Evaluations were carried out over the energy range 6–122 keV for Timepix3 Si and 20 keV–1.332 MeV for Timepix3 CdTe. Based on this experimental procedure, an energy resolution of 2.6 keV (3.4%) at 59.5 keV was observed for Timepix3 Si. For Timepix3 CdTe, this parameter was 5.6 keV (9.4%) at 59.5 keV, 27.24 keV (4.1%) at 661.7 keV, and 47.4 keV (3.5%) at 1.332 MeV. It is the first time that CdTe bump-bonded Timepix3 spectral performances were evaluated for gamma rays above 1 MeV. The reconstruction of the full-energy peak for such high energies is possible due to the ToA information, which allows the identification of all interactions caused by a given gamma ray within the detector.

Abstract

International audience; Caliste HD is a recently developed micro-camera designed for X and gamma-ray astronomy, based on a 1×1 cm$^2$ CdTe Schottky pixelated detector. Its entire surface is composed of 256 pixels, disposed on a 16 × 16 pixel array. This spectrometer is buttable on its 4 sides and can be used to create a large focal plane. It is also designed for space environment. Its IDeF-X front-end electronics has low power consumption, excellent noise performance and a wide dynamic range, from 2 keV to 1 MeV. Moreover, electronic noise performances of this device were optimized to set the low level energy threshold lower than 2 keV.This paper focuses on the Caliste HD performance near the low energy limit. For this purpose, we have exposed the CalisteHD module to a mono-energetic X-ray beam, and set energies between 2 and 12 keV. We measured accurately the detectionefficiency in this energy range and found it to be ranging from 39% to 75% for energies from 2.2 keV to 11.6 keV, consideringonly particles detected in the single-event photopeak and ignoring events impinging between two adjacent pixels. Thisefficiency detection profile thereby highlights crucial effects of the Pt electrode opacity on Caliste HD low energy response, andsuggests the presence of absorption zones at the interface between CdTe crystal and platinum. Respective thickness of eachlayer were estimated by simulation and confirmed by RBS ($Rutherford\ Backscattering\ Spectroscopy$).Besides, using a mono-energetic beam allows fine energy resolution measurement, which was found to be ranging from560 to 760 eV FWHM between 2 and 12 keV. In addition, the linearity of this spectrometer and the issue of charge sharingbetween adjacent pixels were studied. This study revealed that spectroscopic performances remain excellent for such boundaryoperating conditions.
