Welcome to the Wiki of the Vacuum Ultra Violet experiment, below you will find details about the experiment such as manuals and measurement data, as well as presentations about this setup.
Possible experiment names (most are not great, some are terrible):
DUVET - Detector-material UV ExperimenT
MAUVE - MAterial UV Experiment
VULTURE - Vakuum Ultraviolettes Licht Transmission(?) Und Reflexion Experiment (excuse my German..)
ULTARE - Ultraviolet Light Transmission And Reflection Experiment
SUMO - Scintillation Ultraviolet Material Optics
CHMOD - CHaracterization of Material Optics for Detectors / CHaracterization of Material of Other Detectors
SOUVENIR - Scintillation Optics UV Experiment ... ??
VUVUZELA - Vacuum UV ..??... Experimental Light Assesment
VULCANO - Vacuum Ultraviolet Characterization At Nikhef ...??
Goal of the experiment
With the VUV experimental setup we would like to learn more about the optical properties of materials for scintillation based time projection chambers (TPC). We want to measure fluorescence, reflectivity and transmittivity of PTFE under UV light in vacuum. Eventually, we would like to also cool our samples to better simulate the environment inside a TPC.

The working of the experiment as well as the to-do's are explained on this page.
Components of the experiment
McPherson Monochromator and attachments
Ideal vacuum vacuum chamber
Source code overview
We are using python for the source code running on the Raspberry Pi for both UI and data acquisition (apart from the Arduino sketch written in C++).
The code can be found at https://gitlab.nikhef.nl/vgupta/vuv.
