Description
We present the recent development of a lightweight detector capable of accurate spatial, timing, and amplitude resolution of charged particles. The technology is based on double-sided double-metal p+-n-n+ micro-strip silicon sensors, ultra-light long aluminum-polyimide micro-cables for the analogue signal transfer, and a custom-developed SMX read-out ASIC capable of measurement of the time ($\Delta t\simeq 5\,\mathrm{ns}$) and amplitude. Dense detector integration enables material budget $>0.3\%,X_0$. The sophisticated powering and grounding keeps the noise under control.
In addition to its primary application in Silicon Tracking System of the future CBM experiment in Darmstadt, our detector will be utilized in other research applications.
Summary (500 words)
We present the recent development of a lightweight silicon micro-strip detector (DSSD) with the capability for accurate spatial, timing, and amplitude resolution of charged particle interactions. The technology is based on a $300\,\mathrm{\mu m}$ double-sided double-metal $p^+-n-n^+$ micro-strip silicon sensor of various form-factors, ultra-light long aluminum polyimide micro-cables for the analogue signal transfer, and a custom-developed STS-MUCH XYTER (SMX) read-out ASIC capable of simultaneous measurement of the time ($\Delta t\simeq 5\,\mathrm{ns}$) and amplitude ($0.1-100.0\,\mathrm{fC}$) of the interaction with the incident particle.
The detector assembly features dense integration, enabling a reduction in material down to $0.3\%,X_0$ in the sensitive area. The read-out electronics, along with their associated support and cooling interfaces, can be located up to $500\,\mathrm{mm}$ away. The sophisticated powering and grounding concept of the detector reflects the necessity of synchronous reading of the both sides of DSSD sensor while also keeping the electronics noise under control.
In addition to its primary application in the Silicon Tracking System (STS) of the future heavy-ion fixed target Compressed Baryonic Matter experiment in Darmstadt, Germany, our detector is also being utilized in various research applications, such as the Tracker of the E16 hadron experiment at J-PARC and the \textsc{Strasse} tracker at the Radioactive Isotope Beam Facility at Riken in Japan. We also are exploring opportunities to expand its use to medical imaging, where the unique features of our detector could prove to be essential.
