SoLID Pre-R&D
The Goal of the pre-R&D plan for the SoLID spectrometer is to mitigate the primary technical, schedule and cost risks in advance of the project start. These risks are due to the large scale of the project, as well as the requirement for operation at high luminosity. The pre-R&D plan covers the high rate electronic and DAQ system and the gas Cherenkov detectors which are two systems with identified potential risks.
For the DAQ system, there are two main issues. First, the initially proposed readout chip for the GEM readout in the earlier version of the SoLID pre-CDR is obsolete and a new modern chip has been identified as a suitable replacement. The pre-R&D tests will allow us to be sure the new chip based readout system satisfy the SoLID DAQ requirements. Second, we need a small-scale test stand of the DAQ system to study the DAQ system performance and support the detector tests in order to find out if they will be able to meet the demanding requirements in the high-rate environment. This will impact the trigger and readout of the major systems, including the gas Cherenkovs (light and heavy), calorimeter, and time-of-flight detectors.
The gas Cherenkov detectors are critical for creating efficient triggers and providing particle identification in the high-rate environment of SoLID. The SoLID light gas and heavy gas Cherenkovs designs use square shaped photosensors known as multi-anode photomultiplier tubes (MaPMTs) in order to cover a large area through tiling. The high level of pixelization of the these photo sensors can potentially help reduce backgrounds. We plan to build and test a telescopic Cherenkov device to verify that the proposed Cherenkov detectors can reach the desired performance in the high-rate environment. The available granularity of the photosensors can provide an improved performance in rejecting background in the harsh environment of high luminosity.
