New chemical approach to increase the refractive index, which is a key parameter of aerogels for Cherenkov radi-
The so-called chemical approach is based on the introduction of additives into the SiO2 airgel, increasing the refractive index. DLC anode well electron multiplier - a key element of fast and robust position-sensitive micro-patterning.
The Well Electron Multiplier with DLC anode – a key ele- ment of the fast and robust position sensitive micro-pattern
Here we present a description of various approaches for increasing the refractive index using thermal sintering of blocks [2], the pinhole method (microholes) [3], including the original chemical approach developed by us based on the sol-gel method. The introduction of a few mole percent can increase the refractive index by a few hundredths of a unit.
Signal shapes in the Well Electron Multiplier with DLC anode
To increase the number of registered Cherenkov photons and extend the range of particle identification in the direction of small pulses, it is necessary to obtain blocks of airgel with a refractive index above 1.07 without deteriorating the optical properties (scattering length, light absorption). length and uniformity of refractive index in the layer). For example, this is zirconium dioxide (ZrO2), whose refractive index is 2.23; by comparison, SiO2 has a refractive index of 1.45.
