Target Fabrication is a group at the Central Laser Facility responsible for providing complex objects for use in high-power laser experiments. These objects are at the focal point of high-intensity laser interactions and are made into complex geometries from novel materials. Target requirements are dependent on experimental requirements and vary broadly from one experimental campaign to the next; the experiments topics span plasma physics and particle acceleration, laboratory astrophysics, and industrial applications opportunities.
In order to create extreme environments the laser is focused to an interaction point comparable to the width of a human hair, the targets that are required have features of the same magnitude. On this scale manufacture and quality control is extremely challenging! Target Fabrication requires a wide capability of physical and chemical processes, together with advanced characterisation techniques to deliver targets that meet the experiment’s requirements.

Summary of Key Duties & Responsibilities
Are you studying a degree related to MEMS (Micro-electromechanical systems) or closely related to Physics/Engineering?
The placement student at Target Fabrication will be tasked with developing Target Fabrication’s ability to produce and deliver nanometre-thick foils to laser experiments. These foils will be manufactured using a combination of wafer-baser MEMS technology and thin-film coating. Target Fabrication has a key deliverable for EPAC in the next 3-5 years of supporting high-repetition rate laser experiments; delivering thousands of batched produced targets to operations. This project will aim to reach this goal and increase the capability of Target Fabrication to produce such targets.
Responsibilities will include:
Support the group in a wider sense by operating thin-film coating equipment for complementary projects.
Demonstrate manufacture of targets using MEMS-based wafer processing and thin-film coating
Improve the yield of suspended films over apertures by implementing engineering solutions
Quality control the resultant targets using scientific equipment including techniques such as AFM, SEM and interferometry
Work in a clean-room laboratory environment
Complete project documentation by tracking progress against milestones
Use CAD skills to assist the wider group with 3d design
In order to apply for this role you must have:
At university, enrolled on an undergraduate degree course and required or have requested to take a year out of studies to gain experience within industry
Right to live and work in the UK
