USER AND BEAMTIME STATISTICS
Table 2 gives a summary of instrument performance for 2019. Approximately 2 649 days were made available to our users in 2019 on ILL and CRG instruments (either via standard request or via the EASY and DDT routes), which represents about 78 % of the beamtime available. A total of 91 days was used by ILL scientists to carry out their
own scientific research. About 10 % of the total beamtime available on the ILL instruments was allowed for tests, calibrations, scheduling flexibility, recovery from minor breakdowns and student training. Finally, a total of 329 days were lost as a result of various malfunctions, which represents less than 10 % of the total beamtime available.
In 2019, the reactor operated for two of the originally planned three cycles. This represents 101 days of neutrons, during which a total of 625 experiments were performed (including 14 DDT, 99 EASY and 24 internal research experiments). Beam days given to science (used for users and internal research) in 2019 totalled 2 740 (84 % of the total days available).
