N1 - Funding Information:
The wet silica gel production and optical measurements of the aerogel tiles were performed at the Venture Business Laboratory of Chiba University and the High Energy Accelerator Research Organization (KEK), Japan, respectively. The authors are thankful to them both for their support. Profs. I. Adachi of KEK and H. Kawai of Chiba University are thanked particularly for their help in aerogel fabrication and measurements. We are grateful to Tatsumi Kakou Co. Ltd. Japan, for their contributions to the water-jet machining. This study was supported by a Grant-in-Aid for Scientific Research (C) (No. 18K03666) from the Japan Society for the Promotion of Science (JSPS).

N2 - This paper reports the successful fabrication of silica aerogel Cherenkov radiators produced in the first batches from a 96-tile mass production performed using pin-drying technique in our laboratory. The aerogels are to be used in a ring-imaging Cherenkov detector in the spectrometer of a planned balloon-borne cosmic-ray observation program, HELIX (High Energy Light Isotope eXperiment). A total of 36 transparent, hydrophobic aerogel tiles with a high refractive index of 1.16 and dimensions of 10 cm × 10 cm × 1 cm will be chosen as the flight radiators. Thus far, 40 out of the 48 tiles fabricated were confirmed as having no tile cracking. In the first screening, 8 out of the first 16 tiles were accepted as flight-qualified candidates, based on basic optical measurement results. To fit the aerogel tiles into a radiator support structure, the trimming of previously manufactured prototype tiles using a water-jet cutting device was successful.
