New detectors for the ALICE experiment: From Darmstadt to Wonderland
The particle accelerator Large Hadron Collider at the European Organization for Nuclear Research CERN will end its second running period with a heavy-ion run, colliding lead nuclei (Pb), starting in November. After a subsequent long shutdown, in 2021 the accelerator will resume operation with an increased luminosity. In order to fully benefit from the expected rate of 50,000 Pb-Pb collisions per second, the ALICE experiment is currently upgrading its detectors. The ALICE group at GSI is on the forefront of this activity.
The ALICE group among others assembles twenty new readout detectors for the Time Projection Chamber which is the heart of the ALICE apparatus. After four years of intensive work, the last five detectors were delivered to CERN at the end of October. The production took place in the GSI Detector Laboratory, strongly profiting from – but also helping to further extend – its excellent infrastructure. (OeA)
