A transfer storage CRT is a variant of direct-view storage cathode ray tube that includes a separate, fast-responding internal storage mesh to increase writing speed.
The "image" on the fast mesh would decay too quickly for direct viewing, however, therefore it is transferred to the main storage target in a separate step.
Transfer storage CRTs (e.g. the T7630) are used in Tektronix scopes that have "fast" storage modes, such as the 7623, 7633, 7834 and 7934.
In fast mode, the time base is inhibited after a sweep, and the transfer cycle is started. Individual sweeps therefore occur in about one-second intervals.
The first transfer storage tube was the T7410 developed by Tektronix in 1972 for use in the 7623 (See Keller, p.131+).
