Technician in Particle Physics - Grade 5/6

You will join the particle physics group working closely with academics, physicists, and mechanical and electronic engineers. You will be based in the Liverpool Semi-conductor Detector Centre cleanroom complex within the Department of Physics at Liverpool. You will join a team of physicists and engineers working together on the manufacture and quality-control testing of silicon detectors for the DarkSide-20k international dark matter experiment that we take place at the INFN Gran Sasso Laboratory in Italy. You will assist in the assembly and testing processes for bonding assemblies of SiPMs to PCB substrates to produce in total 2400 low radioactivity SiPM array “tiles” to instrument the DarkSide-20k outer detector. A hands-on approach is expected in areas such as prototyping, assembly and testing of structures, both on-site and possibly during installation and commissioning at external experimental facilities.

You will check the quality of die-bonding through optical inspection and wire-pull tests using industry-standard equipment. You will have to monitor and report yields, machine problems and the usage of consumables. You will be expected to attend technical meetings at Liverpool and occasionally off-site as the project proceeds.

You should be educated to higher BTEC or degree level in Electrical or Mechanical Engineering (or have equivalent professional experience). This role requires the highest standard of cleanroom working disciplines to be applied. You will be required to work from formal engineering drawings and specifications. Good sensory and physical co-ordination is essential given the small scale and delicate nature of the detectors. Past experience of working in a clean room environment and on wire-bonding are highly-desirable. You will have good communication skills and the ability to instruct others (e.g. students) in the production procedures.

This post coincides with 2 years of the production phase of the DarkSide-20k outer detector. Subject to funding availability, there could be future possibilities of employment within the Department on other projects requiring similar skills and experience. The post is available for 2 years.
