Priya Singh,Sanjeeb Kumar SahooCrowe ceils [.], and the continuous-sheet memory [.], Problems have been slow speed, large heat production, or close tolerance requirements. Currently, crossed-film cryotrons and the continuous-sheet memory appear the most promising.

P. Gopinath,S. Uday Kumar,Poornima Dubeyure phenomena was brought about by the development and widespread use of the A. D. Little-Collins helium cryostat. This enabled the attainment of cooling loads one or two orders of magnitude greater than could have been previously contemplated. Inevitably, cooling demands have risen, so that now it
