Abstract
The NA61/SHINE experiment studies hadron production in hadron-hadron, hadron-nucleus and nucleus-nucleus collisions. The physics programme includes the study of the onset of deconfinement and search for the critical point as well as reference measurements for neutrino and cosmic ray experiments. For strong interactions, future plans are to extend the programme of study of the onset of deconfinement by measurements of open-charm and possibly other short-lived, exotic particle production in nucleus-nucleus collisions. This new programme is planned to start after 2020 and requires upgrades to the present NA61/SHINE detector setup. Besides the construction of a large acceptance silicon detector, a 10-fold increase of the event recording rate is foreseen, which will necessitate a general upgrade of most detectors.
Highlights
The NA61/SHINE experiment [1] is preparing for a 10-fold increase of the read-out rate to satisfy the requirements for the proposed physics programme [2] after CERN long shutdown 2, in particular related to the open-charm measurement with the vertex detector (VD)
This requires an upgrade of most detectors and other sub-systems of the NA61/SHINE experiment
Development and implementation of new detector control system (DCS): The new readout system requires a considerable extension of the existing NA61/SHINE DCS system to make full use of the information supplied by the FECs and the RCUs
Summary
The NA61/SHINE experiment [1] is preparing for a 10-fold increase of the read-out rate to satisfy the requirements for the proposed physics programme [2] after CERN long shutdown 2 (beyond 2020), in particular related to the open-charm measurement with the vertex detector (VD). Laboratory tests of the new readout chain: Tests of the readout of several FECs in the lab using the full read-out chain (FECs, flexible cables, small adapter boards, RCU2s) will be performed These tests will be repeated with FECs connected to the upstream corner of one MTPC chamber with beam in order to see real track signals. The increase of the lead ion beam intensity by more than one order of magnitude (up to 105 ions per second) requires upgrades of the radiation hardness and protection as well as of the readout rate of the PSD. The precision of the reaction plane determination for Pb + Pb collisions at 150A GeV/c with the present PSD and with the two calorimeter setup is shown in Figure 20 left and right, respectively. One concludes that the precision of the reaction plane determination for semi-peripheral collisions remains almost unchanged
