The aim of the CMS tracker upgrade campaign is to find a new radiation hard sensor material for the HL-LHC upgrade of the CMS tracker. Different test structures and sensors were implemented on a variety of silicon materials with different thicknesses by Hamatsu Photonics, Japan. Samples have been irradiated to fluences up to 3E15 with protons at Karlsruhe and the CERN PS and with reactor...

There are a number of plausible candidates for sensor types in the outer regions of HL-LHC trackers, where issues of cost and ease of construction must also be taken into consideration given the very large number of sensors that are required. Over the last couple of years, the CMS experiment has undertaken 4 beam tests to probe the radiation hardness of prototype strip sensors procured from a...

CMS plans to increase both its luminosity and center of mass energy in future upgrades. As such, more radiation hard silicon must be used for the inner tracker. The HPK campaign aims to determine which sensor material, polarity and geometries will work best under these high radiation conditions. One of Brown Universities' contributions to this project includes charge collection efficiency...

Silicon pixel modules employing n-in-p planar sensors with an active thickness of 150µm were assembled with the new FE-I4 ATLAS readout chips an irradiated up to a fluence of 4e16 n_eq cm^-2
These thin sensors are designed as candidates for the ATLAS pixel detector upgrade at HL-LHC, as they ensure radiation hardness at high fluences.
High precision beam test measurements of the hit...

We will report about the characterization of FE-I3 and FE-I4 active edge planar n-in-p pixels produced at VTT, Finland. The sensor thickness is 100 um and different geometries of the sensor edges have been implemented, down to an inactive width of only 50 um. The charge collection properties before and after irradiation have been studied with radioactive sources and analysis of beam tests at...

A test beam telescope has been built using the ALIBAVA system to drive its
data acquisition. The basic telescope planes consist in four XYT stations. Each
station is built from a detector board with two 80-micron-pitch sensors,
mounted one in each side and their strips crossing at 90 degrees. The
ensemble is coupled to an ALIBAVA daughter board. These stations act as
reference frame and...

We are working on the proposed "BeamCal" project. Its goal is to detect scattered incoming beams at ILC at small angles, to prevent the background from two-photon processes to mimic signatures of new discoveries. The detector, which is envisioned as a tungsten sandwich calorimeter, will be subject to high fluences EM radiation that will shower in the tungsten radiator. We plan to do studies...

We explore the concept of using a deep-submicron HV CMOS process to produce a drop-in replacement for traditional radiation-hard silicon sensors. Such active sensors contain simple circuits, e.g. amplifiers and discriminators, but still require a traditional (pixel or strip) readout chip. This approach yields most advantages of MAPS (improved resolution, reduced cost and material budget,...

The Real Time Wide Area Radiation Surveillance System (REWARD) is a novel mobile system for radiation detection and monitoring based on the integration of two new miniaturized solid-state radiation sensors. One sensor is a Cadmium-Zink-Telluride ((Cd,Zn)Te or CZT) detector for gamma radiation with precise energy measurement to identify the emitting isotope. The CZT detector unit is made in...
