As part of its detector development programme, ISIS manufactures a range of in-house detectors, including wavelength-shifting fibre (WLSF) based scintillation detectors, which are critical for capturing and characterising neutron interactions with high spatial and temporal resolution. A key component of these detectors is the neutron scintillator screen which is composed of a zinc sulphide silver activated phosphor and an enriched lithium-6 fluoride neutron-sensitive converter material. Following neutron capture in the converter, light is emitted from the phosphor subsequently collected by wavelength-shifting fibres and guided to photodetectors for signal processing. The quality, consistency and performance of the scintillator screen directly impact detection efficiency and effective gamma‑ray and background discrimination. To support new detector builds, particularly for the HRPD-X, SANDALS II and WISH II instruments, a framework contract is required to ensure a reliable supply of high-performance ZnS:Ag/6LiF screens that meets the stringent technical and operational demands of ISIS instruments. These screens must be provided in different shapes, sizes and thicknesses to match the range of instrument beamline geometries and neutron fluxes encountered at ISIS. Some of the screens will be operated in vacuum and must be capable of maintaining performance within a vacuum environment for the lifetime of the detector, typically 15 years. The purpose of this tender is to guarantee a steady supply of ZnS:Ag/6LiF neutron scintillator screens to cover the needs of the ISIS Endeavour Programme, a 10-year programme to upgrade the suite of ISIS instruments. It will ensure a consistent and reliable product is always being provided throughout the programme. It will help to reduce the need for generating repeat tendering and for storing large quantities of product on site until needed. This contract is being awarded following a competitive open tender process. ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** complete - **CPV codes:** 38000000 - **Delivery regions:** UKJ - **Delivery countries in notice:** GB - **Estimated Value:** £1,760,000 - **Contract Period:** 29/03/2026 to 29/03/2030 ## Awards & Winning Suppliers (1) - **Award:** UKRI-5382 ZnS:Ag/6LiF Neutron Scintillator Screens (active) - Award id: `1` - Supplier(s): **Scintacor Limited** - Supplier identifiers: `GB-FTS-167837` - Value: £1,760,000 (exc.
