Dual growth chamber Molecular Beam Epitaxy System

The System must comprise of:

1. Two vacuum-linked growth chambers with high capacity sources and high speed pumping arrangements suitable for the production of arsenide/phosphide and arsenide/antimonide materials of the highest purity.
2. Dedicated sample preparation chamber for cleaning and oxide desorption using gas sources.
3. A separate outgassing and surface analysis chamber with an Auger Electron Spectroscopy tool.
4. Two sample entry locks, and two storage chambers.
5. Robust automated transfer system connecting entry locks, surface preparation and analysis chambers, storage chambers, and growth chambers with space for further expansion.
6. Reliable automation and control software that allows for the two growth chambers to be operated independently.
7. Low temperature (down to cryogenic) metals deposition capability (either within one of the two arsenide growth chambers or separate), and should ideally fit in a 7.2m by 4.5m footprint (excluding peripheral equipment, such as electrical racks, cryopumps and compressors, PCs, etc.).

It would be advantageous for the System to have the following additional capabilities:

a. integrated vacuum suitcase technology compatible with other UK facilities to allow transport of samples under vacuum in and out of the system.

b. integrated solutions allowing maintenance of critical components without breaking chamber vacuum

real-time data management suitable for machine learning and auto-correction of growth conditions.

We will be looking for a System with:

i. resource-efficient equipment, such as low liquid nitrogen consumption

ii. exemplary after-sales service

iii. advanced equipment monitoring and notification systems, such as power/water/vacuum loss

iv. robust back-up systems for essential supplies, such as power/water. Additional information: Market Engagement: We welcome site visits or virtual meetings from potential suppliers to discuss the System requirements during the period 18th November - 6th December 2024. Meetings and site visits must be arranged no later than 29th November. Subject to successful funding of the System, we expect the tender to be published in January 2025.

The value entered at the top of this notice at I.1 was £5,000,000, however the overall range we are considering for the budget is +/- £1m of this figure, depending on any additional features chosen.

Format: individual meetings, either on-site or virtual.
