Despite all the skiing I documented during my year, I also did manage to get plenty of work done!
I was involved in two major projects at CERN. I was responsible for designing and manufacturing a 1:1 scale integration model of part of the detector for cooling and testing purposes. My tasks included:
- Ensuring services can be routed in given space
- Installation sequence of cooling pipes, services and thermal screen (troubleshooting)
- Thermal screen integration model consideration
- Mock rotation and transport sequence tasks
- Creation of CAD designs
- FEA analysis structural integrity
- 2D technical drawings
- Liaising with manufacturer and developing construction sequence

Alongside this, I co-designed the services feedthrough design proposal for the HGCAL Endcap for the Phase 2 LHC. My roles for this project included:
- Service feedthrough methods and sealing functions
- Routing of services inside cold volume (compatible with assembly sequence layer by layer, and optical and CO2 installed last)
- Routing of services outside the cold volume into the cable channels on top of the endcap nose brackets
- Packing factor of cables and layout efficiency
- Connector options
- Heat transfer calculations and simulations experience based on copper cross section and feedthrough materials
Culminating in a 3D CAD model integrated into the master CMS HGCal assembly as seen below
