The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S) events in its decade of operation. Super-KEKB, an upgrade is under construction, to increase luminosity by two orders magnitude during a three-year shutdown, with ultimate goal 8E35 /cm^2 /s luminosity. To exploit increased luminosity, been proposed. A new international collaboration Belle-II, being formed. Technical Design Report presents physics motivation, basic methods accelerator upgrade, as...
Abstract The ATLAS experiment is constructing new all-silicon inner tracking system for HL-LHC. strip detectors cover the radial extent of 40 to 100 cm. A approach adopted use p-type silicon material, making readout in n + -strips, so-called -in-p sensors. This allows enhanced radiation tolerance against an order magnitude higher particle fluence compared LHC. To cope with varying hit rates and occupancies as a function distance, there are two barrel sensor types, short strips (SS) 2 long...
Compton Cameras emerged as an alternative for real-time dose monitoring techniques Particle Therapy (PT), based on the detection of prompt-gammas. As a consequence scattering process, gamma origin point can be restricted onto surface cone (Compton cone). Through image reconstruction techniques, distribution emitters estimated, using cone-surfaces backprojections cones through space, along with more sophisticated statistical methods to improve quality. To calculate required reconstruction,...

In order to exploit the advantages of ion-beam therapy in a clinical setting, delivery verification techniques are necessary detect deviations from planned treatment. Efforts currently oriented towards development devices for real-time range monitoring. Among different detector concepts proposed, Compton cameras employed prompt gammas and represent valid candidate verification. We present first on-beam test MACACO, telescope (multi-layer camera) based on lanthanum bromide crystals silicon...

The production of strip sensors for the ATLAS Inner Tracker (ITk) started in 2021. Since then, a Quality Assurance (QA) program has been carried out continuously, by using specific test structures, parallel to Control (QC) inspection sensors. QA consists monitoring sensor-specific characteristics and technological process variability, before after irradiation with gammas, neutrons, protons. After two years, half full volume reached we present an analysis parameters measured as part process....

Given the strong variations in sensitivity of Compton cameras for detection events originating from different points field view (FoV), correction is often necessary image reconstruction. Several approaches calculation matrix have been proposed literature. While most these models are easily implemented and can be useful many cases, they usually assume high angular coverage over scattered photon, which not case our prototype. In this work, we derived an analytical model that allows us to...
