Objectives:
1) Realise a compact vacuum chamber for a Sr optical lattice clock
Based on the previous experience of UoB, the DC will build a compact, robust vacuum chamber suitable for a Sr optical lattice clock. Task 1: The DC will build a vacuum chamber that will contain a lattice enhancement cavity to enable a moderately low power diode laser source to be sufficient to generate a repeatable high-quality optical lattice potential with well-controlled trapping parameters.Task 2: They will also produce a suitable coil design and thermal control to ensure a homogeneous temperature environment for reduced blackbody radiation shift uncertainty. Task 3: The DC will then integrate a strontium atom source, a compact Zeeman slower and a light distribution system into the vacuum chamber.
2) Demonstrate functionality through clock spectroscopy
Task 4: In order to validate and demonstrate functionality, The DC will perform first stage and second stage laser cooling to successfully trap strontium atoms within the MOT. Task 5: Finally, the DC will perform clock spectroscopy on the trapped strontium atoms using a clock laser already available in the lab.

Objectives:
1) Test and validation of existing field deployable optical clock
UoB focuses on compact and field deployable quantum clocks. One such setup under development is a rack mounted field deployable strontium optical clock aimed at better than 1 part in 10<sup>16</sup>. By the time the DC joins the team, the setup is expected to be functional and ready for test and validation. Task 1: The DC will perform stability comparisons with the stationary laboratory-based optical clock setup. The measurement campaign will consist of both synchronous and asynchronous configurations.
2) Clock comparison with Partner clocks
UoB is connected to Paris and PTB via fibre. Task 2: The DC will extend the measurements to include comparisons with optical clocks in Paris and at PTB. Task 3: Finally, the DC will operate the setup outside of the lab in order to demonstrate transportability as well as field deployability,by taking the system to LTE or PTB for comparisons.
