 cm radius
-cm barbox length
-barboxes, 5 long radiator bars side-by-side in a barbox
-Radiator bar: 10 x 35 x 2900 mm3 (T x W x L) (2-3 shorter bars glued together)
-Focusing optics: �	Radiation-hard 3-layer spherical lens
-Expansion volume: �	Solid fused silica prism: 24 x 18 x 30 cm3 (H x W x L)�	Additional longitudinal space for MCP-PMTs, readout cards, cables: ~13cm
-Readout:�	12 commercial MCP-PMTs per prism, total 49k channels readout by hpDIRC
-Number of sectors, barrel radius and bar length can be still optimized for �	integration, PID performance largely independent of barrel radius and bar length
-Expansion volume shape can be optimized for MCP-PMT magnetic field �	performance (tilted backplane)
