The experiment was limited to about 12 days of data due to mechanical problems with the cryostat that surrounded the liquid helium targets, in addition to the relatively long fill and drain times (approximately 30 s to fill and 120 s to drain) of the target chambers needed to switch between polarimeter states, compared to the 600 s data acquisition time for any given polarimeter state.
