Increase of incidents due to MACS, M1 and EMIR. For MACS and
M1 there have been serious breakdowns. MACS suffered two
catastrophic failures: The breakage of the cable rotator due to a
blocked hose, and the breakage of the Azimuth motor due to
interference from a screw in the permanent magnets.
Operations – Statistics #2

Technical losses: Accumulated average (March. 1st, 2021 – August 15st) 7,89 %
Operations – Statistics #3

Optical Quality of the Telescope: Global Reflectivity (650nm – M1·M2·M3) > 62,0 %
Remplacing Primary Mirror Segments: (Segments Changed March. 2021 – Sep. 2021) 14 units (18 in 2017)
(36 in 2018 !!!)
(18 in 2019)
(20 in 2020)
Maintenance
Sep. 2021 GRANTECAN S.A. Page 6
▪ PRIMARY MIRROR (M1):▪ Water leak in manifold for HiPERCAM affects M1 surface. Resolved.
▪ ACQUISITION AND GUIDANCE (AG):▪ Problems in Nasmyth A and NB (simultaneously). Resolved.
▪ HYDROSTATIC BEARING SYSTEM:▪ Control firmware update. Monitoring Improvements.
▪ MAIN ELECTRICAL SYSTEM:▪ Improvements and obsolescence correction (Main Switch & UPS
networks upgrades - ongoing).
▪ OTHERS:▪ Maintenance of Dome Shutters (Summer).
▪ Heavy maintenance of main cooling water pumps.
▪ Big (10 years) maintenance of lift work platforms.
▪ MACS:▪ Two critical failures at Azimuth. Recovered. Collateral: Occasional oscillations under study.
Maintenance – Instruments
Sep. 2021 GRANTECAN S.A. Page 7
OSIRIS: The instrument has behaved well.
• Several tests for MAAT just before retirement.
• It has been removed from the telescope.
• Several maintenance operations are planned, taking advantage
of the shutdown (Cryostat, cooling, etc.).
HiPERCAM: Reintegrated in May. Dismantling today.
• A cool head was repaired. Successful operation.
• Dismantling -> Starts the Half Moon Platform integration.
EMIR: Is operative.
• Problems in the DAS and the detector. Addressed but not solved.
• Problems in a bar (MOS Slit). Shortcut to solve it.
MEGARA: Is operative (IFU)
• Successfully replaced the pseudo-slit.
• Cryogenic cycling carried out correctly.

ICTS:▪ M1: Received Edge Sensor Processors (ACP). Concluding work on nodal boxes.
▪ ISS: (Interlock & Safety System): Delays due to factory shutdowns (automations).
▪ Instalación Conectada (Industrial IoT for enviromental data): On going.
MECON:▪ Scientific Archive and Backup: In installation and configuration.
▪ Network Security and Access Control: In production. Configuration 1.0.
▪ HCI System & New Wi-Fi: Preparing for tender.
▪ Upgrade Coating Chamber: Tender awarded (VTD)
▪ Air Compressors: In production. Completed.
OTHERS:▪ Solar Plant: Tender awarded (ELECNOR)
▪ UPS (Safety Electricity): Tender awarded (ELECNOR).
▪ Electric Mobility 2.0: Under Tender.
▪ New Storage Hall (sea level): In negotiations (near to Garafía Town Hall).
▪ Helium for Frida and Miradas: Preparing hose outbaking. Next hoses reception.
▪ Civil works reforms in GTC: Starting...
