The Centre posses and maintains a leak-tester instrument, which is used regularly across the beam-lines. However, in-order to support research internal to the Cavendish laboratory, the Centre is happy to lend the leak-tester to other users. In support of the maintenance and replacement costs, using the leak-tester is charged at £50/day. A formal costing model […]
The transition from reading textbooks as an undergraduate to completing novel research can be met with difficulty. To ease this transition, an educational package for atom scattering was written in the Summer of 2020. This consists of a set of useful topical notes; a collection of basic research tasks; and their full solutions (including MATLAB […]
MoBSTer is an open-source software, written to allow the design and accurate simulation of molecular beam scattering apparatus through the joining of modular instrument functions. The software allows users to calculate the propagation of particles through their scattering machines, and test new instrument ideas in context. MoBSTer makes no assumptions about the 3D geometry of […]
PIGLE (Particles Interacting in Generalized Langevin Equation simulator) is a fast simulator for the dynamics of multi species interacting particles responding to a 4D potential energy surface (3 spatial dimensions and one dimension for rigid body rotations), obeying the generalized Langevin Equation, $$m\ddot{\mathbf{x}}_i = -\nabla V[\mathbf{x}_i(t)] – m\int_{-\infty}^t \gamma_i(t – t^\prime)\dot{\mathbf{x}}_i(t^\prime) \mathrm{d}t^\prime + \zeta(t) + […]
