The Pressure and Furnace team have chosen to highlight a new starter and the development of a system for control of humidity of flow gas during in-situ chemical reactions.

The Pressure and Furnace group is continuing to support the user programme.
New Starter
Kimberley Greenough has recently joined the Pressure and Furnace Section as a support technician.
“Previously I worked at Martin-Baker as a Pyro Technician, where my duties involved CNC fuel cutting of solid dual-based fuels and building parachute deployment, under-seat, and canopy jettison rocket motors. I also worked as a firefighter on the aviation fire team where I would oversee live test ejections from zero-zero or low altitude flights and respond to all aerodrome incidents. I am really looking forward to meeting everyone over the coming months and seeing what new opportunities wait for me with my new role in the Pressure and Furnace team”.
Kim will be bringing her existing knowledge and experience from previous employment as well as gaining new skills to enable her to provide technical support to the many gas handling, high pressure and high temperature experiments conducted at ISIS.
Humidity System
In-situ Chemical Reactions with Humidified Gas Flow
A new system has been developed in the pressure and furnace section to enable the humidity of a flowing gas to be measured and controlled.
This is achieved by using an SHT85 humidity and temperature sensor, along with the existing saturator system that produces humid
gas by flowing the gas through a heated water chamber and flow controllers. Two gas flows are merged, one dry gas, one humid gas, to enable the humidity level to be controlled. This project was worked on by Adam Sears, Chris Goodway, Keith Allum and Isis design group.

The In-situ humidity gas flow system.
The in-situ humidity gas flow system has an operating range of 5%RH to 80%RH and can be controlled to percentage steps within the operating range of 1.5%.
System was recently run on HRPD for an in-situ hydration experiment.
