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. [ADD MORE INFO]

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

Hamamatsu deuterium lamp

Pfeiffer vacuum pump

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.
