The layout of the underground cavern at Point 1 of the LHC, featuring the ATLAS experiment represented in black. Additionally, the PX14 and PX16 access shafts are shown. The red-coloured area illustrates the current configuration of the ANUBIS experiment, to be positioned on the ceiling of the ATLAS UX1 underground cavern.

(a) The design of the \proanubis detector, showcasing the positioning of the three integrated tracking layers. (b) The arrangement of the tracker components within the \proanubis setup. At the bottom, three RPCs (a triplet) are shown, followed by a singlet in the middle, and a doublet on top.

One of the gas gaps upon reception at CERN. The white patches on the gas gap mark the positions of the spacers.

The IV characteristics for the \proanubis gas gaps measured at CERN before the detector assembly. Each RPC is uniquely identified by a tag, \eg RPC2.

A picture of the BIS7 type FE board used in \proanubis that handles eight readout channels.

(a) The FE board inside a test box at CERN. (b) The full test setup with a closed test box to avoid any electromagnetic noise interference, a signal generator being used to inject test signals at the input of the FE board via flat ribbon cable, and the GHz resolution oscilloscope used to display output from the FE boards.

The RPC configuration employed at the CERN BB5 lab for efficiency measurements. The experimental arrangement consists of three RPCs stacked on top of each other and connected to FELIX DAQ system to evaluate their performance.

(a) The FELIX DAQ system showing different cards with TDC chips numbered from 1 to 18, a serialiser, an amplifier, a shaper, and a discriminator as well as the PCB BIS7 Pad board on the bench. (b) Three RPCs connected to three cards (9 TDC chips) of the FELIX DAQ setup for efficiency purposes.

(a) A 12~\mm thick aluminium honeycomb structure is used as a dummy singlet to replace one in the frame and prevent any detector movement. (b) An RPC module housing a pair of RPC detectors (a `doublet') within a metal frame to provide mechanical stability and act as a Faraday cage. (c) An example of the gas integration setup box for a triplet RPC configuration, the tubing allows gas flow to the RPCs. (d) HV cables connected via cable connectors to provide HV to individual RPCs.
