We report on the design and laboratory testing of a prototype imaging CZT detector intended for balloon flight testing in April 2000. The detector tests several key techniques needed for the construction of large-area CZT arrays, as required for proposed hard X-ray astronomy missions. Two 10 mm × 10 mm × 5 mm CZT detectors, each with a 4 × 4 array of 1.9 mm pixels on a 2.5 mm pitch, will be mou...

We discuss the properties of cosmic ray nuclearites, from the point of view of their search with large nuclear track detector arrays exposed at different altitudes, in particular with the SLIM experiment at the Chacaltaya high altitude lab (5290 m a.s.l.). We present calculations concerning their propagation in the Earth atmosphere and discuss their possible detection with CR39 and Makrofol nuc...

CMS silicon Tracker alignment consists of three key components: Survey during tracker construction, measurements with the Laser Alignment System during operation and track based alignment. Methods and results are explained in detail, with a special focus on track based alignment due to its enormous complexity and numerical challenges. Presented at Vertex06 – 15th International Workshop On Verte...

We have examined long term changes in signal amplitude gain, energy resolution and detection efficiency for the active components of the PIBETA detector system. Beam defining plastic scintillation counters were operated in a ∼ 1 MHz stopped π + beam for a period of 297 days, accumulating radiation doses of up to 2 · 10 6 rad. Detectors in the charged particle tracking system—a pair of cylindric...

The Miniaturized Detector for Application in Space (MIDAS) is a compact device with dimensions 5 x 1 cm3 which combines position sensitive Si detectors and fast neutrons spectrometer. MIDAS developed purpose to act as linear energy transfer (LET) spectrometer the charged particles measure dose equivalent from both neutrons. It based on fully depleted monolithic active pixel sensors track deposi...

Measurements using the LR 115 solid-state nuclear track detector (SSNTD) depend critically on the removed thickness of the active layer during etching, which cannot be controlled by the etching period alone. For example, the bulk etch rate depends significantly on the strength of stirring during etching. We propose here a fast, inexpensive and nondestructive method based on a color commercial d...
