5.1 Facility uptime/ downtime summary
Year wise summary
| Year | % Downtime | Main Causes of Downtime |
|---|---|---|
| 2020 | 79.1 | Pandemic/EMC1 |
| 2021 | 42.3 | EMC1/Cryo |
| 2022 | 44.9 | Cryo/He Compressor |
| 2023 | 70.1 | Cryo/He Compressor/Long Shutdown |
| 2024 | TODO (Rob Kremers / Marc-Jan van Goethem) | TODO (Rob Kremers / Marc-Jan van Goethem) |
Evaluation criteria for calculating downtime:
- Examine the weeks where the beam was scheduled to be delivered (26 weeks per year).
- Evaluate if it would be technically possible to deliver it or not.
- We ignore if we actually had customers or not.
- Major shutdowns due to technical failure (EMC1 and compressor) are considered downtime.
- COVID period:
- Delays in repairs due to COVID lockdown are considered downtime.
- The machine is up, but customers are not able to travel is considered uptime.
In 2023, the operation periods were limited to January-March and May-June. In June, a prolonged technical shutdown was started, with the goal of restarting beam operation in spring 2024. There were three main reasons for the shutdown's execution.
- Compensation for the maintenance backlog from the past decade and replacement of aged and obsolete components.
- Installation of the beamline components and experimental stations for the IMPACT platform for small animal irradiations, and for the nuclear physics experiment NEXT.
- The electricity price has peaked in 2023. Given the necessity of the shutdown for the two aforementioned reasons, performing it during 2023 has been considered to be financially advantageous for the facility, saving on excessive electric power costs.
