New equipment at GIFT to measure hydrogen desorption, as a function of temperature during the heating of steel samples.
JooHyun Ryu knows how to use this.
This is the furnace and the tube running through the centre would contain the sample.
This is the tube, which is first purged with helium. Heating causes the hydrogen to be dislodged from traps, with the temperature at which it is evicted from the sample related to the potency of the trap.
The expelled gas ends up in the chromatograph
The samples in the envelope are given metallurgical treatments, charged with hydrogen, tested and then the 30 mm gauge length is cut and placed in the tube in the furnace.
The samples are thin so as to allow accurate characterisation of traps
This it the equipment used to charge the steel with hydrogen
This is Ryu
The gas cylinders
These are in Fredric Barlat's office, nothing to do with hydrogen desorption
