We report the successful operation of a functional pixel detector with gaseous helium cooling. Using an accurate mock-up beforehand, cooling was validated. use miniature turbo compressor to propel at $2\,g/s$ under ambient pressure conditions gas temperatures above $0^{\circ}C$. Our earlier results based on computational fluid dynamics simulations and much simpler are confirmed. With this, we paved path cool detectors in experimental particle physics heat densities up $400\, mW/cm^2$ using...
The Mu3e experiment searches for the lepton flavour violating decay $\mu^+ \rightarrow e^+ e^- e^+$ with an ultimate aimed sensitivity of $1$ event in $10^{16}$ decays. To achieve this goal, must minimize material budget per tracking layer to $X/X_0\approx 0.1\,\%$ and use gaseous helium as coolant. pixel detector uses High-Voltage Monolithic Active Pixel Sensors (HV-MAPS) which are thinned down $50\, \mu m$. Both cooling HV-MAPS a novelty particle detectors. Here, work on successfully...
Abstract The Mu3e experiment searches for the lepton flavour violating decay μ + → e - with a target sensitivity of 1 event in 10 16 decays. To achieve this goal, must minimize material budget. pixel detector uses High-Voltage Monolithic Active Pixel Sensors (HV-MAPS) which are thinned down to 50 μm. Combined gaseous helium as low density coolant, results only X/X 0 ≈ 0.1% per tracking layer. Both cooling and HV-MAPS novelty particle physics experiments. Here, work on successfully tracker...
