Scheme of the LN2 circulation. 1: LN2 flux from ESRF tank. 2: pneumatic valve. 3: LN2 Dewar at atmospheric pressure. 4: heater for the N2 cold vapour produced inside the LN2 tank (especially during the refill of 3). 5 and 6: motorized pneumatic valves. 7: monochromator (cf. inset). 8: exit of the N2 cold vapour. Continuous and dashed arrows: liquid and gaseous circulations, respectively. Internal diameter of the LN2 tubes: 15 mm. Inset: LN2 circulation inside the monochromator. 9: thermal bridges. 10: copper heat exchanger. 11: bellows. 12: monochromator rotation axis.
