Solid State Detectors and Tracking for Snowmass

Tracking detectors are of vital importance for collider-based high energy physics (HEP) experiments. The primary purpose of tracking detectors is the precise reconstruction of charged particle trajectories and the reconstruction of secondary vertices. The performance requirements from the community posed by the future collider experiments require an evolution of tracking systems, necessitating the development of new techniques, materials and technologies in order to fully exploit their physics potential. In this article we summarize the discussions and conclusions of the 2022 Snowmass Instrumentation Frontier subgroup on Solid State and Tracking Detectors (Snowmass IF03).

Novel Sensors for Particle Tracking: a Contribution to the Snowmass Community Planning Exercise of 2021

Five contemporary technologies are discussed in the context of their potential roles in particle tracking for future high energy physics applications. These include sensors of the 3D configuration, in both diamond and silicon, submicron-dimension pixels, thin film detectors, and scintillating quantum dots in gallium arsenide. Drivers of the technologies include radiation hardness, excellent position, vertex, and timing resolution, simplified integration, and optimized power, cost, and material.

An Instrument for Precision Controlled Radiation Exposures, Charged Beam Profile Measurement, and Real-time Fluence Monitoring Beyond $10^{16}$ n$_{\textrm{eq}}$/cm$^{2}$

An instrument has been developed for precision controlled exposures of electronic devices and material samples in particle beams. The instrument provides simultaneously a real time record of the profile of the beam and the fluence received. The system is capable of treating devices with dimensional scales ranging from millimeters to extended objects of cross sections measured in tens of square centimeters. The instrument has been demonstrated to operate effectively in integrated fluences ranging up to a few times $10^{16}$ 1-MeV-neutron-equivalent/cm$^{2}$ (n$_{\textrm{eq}}$). The positioner portion of the system comprises a set of remotely controllable sample holders incorporating cooling and interfaces for sample power and readout, all constructed from low activation technologies. The monitoring component of the system samples the current or voltage of radiation tolerant silicon diodes placed directly in the path of the beam.

A Radiation Tolerant Light Pulser for Particle Physics Applications

A light emitting diode (LED) pulser has been developed that can be used for tests or calibration of timing and amplitude sensitivity of particle physics detectors. A comparative study is performed on the components and pulser output characteristics before and after application of 800 MeV protons and cobalt-60 gammas. This device is demonstrated to be tolerant to fluences up to 6.7 $\times$ 10$^{13}$ 800-MeV-p/cm2 and gamma doses up to 5 Mrad.
