The module consists of a glass pressure resistant sphere containing 31 small 3 in.
Several different optical module configurations are under consideration; based on glass pressure spheres containing: a large (10 in).
The base body is a spherical glass pressure housing which contains an internal actuator module, sensors, and an on-board computer.
This contribution presents the first results of a finite element analysis (FEA) performed at CPPM, in association with the Schott glass R&D department, for an alternative low cost glass pressure housing for optical modules in the KM3NeT neutrino telescope.
The RODSS prototype has required a dedicated design work for all its components: it consists of a 5m long fiber glass pressure vessel, which contains all working apparatuses (osmotic modules, desalinated water storage tank, sea water circulation pump, desalinated water delivery pump, flow meters, temperature and pressure transducers, etc).
An IceCube string is composed of 60 digital optical modules (DOMs) each of which is an integrated package of a large area photomultiplier tube, high voltage unit, LED flasher calibration board, and embedded digital data acquisition system encased inside a glass pressure housing.
The biomass was soaked in Milli-Q water overnight in glass pressure tubes (Chemglass) and transferred to a fluidized sand bath at 80°C for ten minutes.
for 30 min in a sand bath using glass pressure tubes (Chemglass, Vineland, NJ, USA) to fully hydrolyze polyfuctose molecules as per Penner [ 30].
0.1 g ball-milled biomass of each species was pre-soaked in dilute sulfuric acid (0.03% w/w, 2 mL) (VWR, Radnor, PA) for 30 min in a 20 mL glass pressure tube (Ace Glass Incorporated, Vineland, NJ).
