ALICE upgrades during the LHC Long Shutdown 2
A Large Ion Collider Experiment (ALICE) has been conceived and constructed as a heavy-ion experiment at the LHC. During LHC Runs 1 and 2, it has produced a wide range of physics results using all collision systems available at the LHC. In order to best exploit new physics opportunities opening up with the upgraded LHC and new detector technologies, the experiment has undergone a major upgrade during the LHC Long Shutdown 2 (2019–2022). This comprises the move to continuous readout, the complete overhaul of core detectors, as well as a new online event processing farm with a redesigned online-offline software framework. These improvements will allow to record Pb-Pb collisions at rates up to 50 kHz, while ensuring sensitivity for signals without a triggerable signature.
The United Kingdom SATMaP program
Data from test tapes from the United States (specifically the August Arkansas scene) and the first tape of the UK test site which came from ESRIN are analyzed. Methods for estimating spatial resolution are discussed and some preliminary results are included. The characteristics of the ESRIN data are examined and the utility of the various spectral bands of the thematic mapper for land cover mapping are outlined.
