For a long-time operation, the heating of cavity mirrors can be non-uniform.
A notable observation drawn from a long-time operation indicates the CH3I treatment strongly restrained the formation of HCOOH that had gradually increased with time-on-stream (TOS).
The tests also include a long-time operation at the maximum current of 18.2 kA to demonstrate the steady state operation capability of the HTS CLs.
It demonstrates that the degradation of HZO-TFT is slower than that of ZnO-TFT under a long-time operation.
A muon detector requires: (1) the capability to track the arriving angles of cosmic-ray muons; (2) a segmented system comprising assembly-type modules, which enables any problem in the system to be identified by monitoring each module, so that a stable long time operation is possible; (3) the capability to eliminate soft component background (Tanaka et al., 2001).
A high-Tc rf SQUID NDE system was developed for stable, long time operation in a noisy environment.
In parallel, to ensure long time operation and to prevent undesirable performance degradation, a shutter system was also implemented in order to reduce impurity deposition on in-vessel mirrors but also to allow in situ transmission calibration.
A device itself has to be faced with many operation problems such as harsh operating environment and aging of components resulted from device's long time operation, possibly becoming contribute factors to hidden failures too.
In the last years more experience has been achieved with long time operation of solar tower receivers increased in size.
The backfire of gas fluidized bed furnaces often occurs with the premixing of air and gas after long time operation at high temperature is prevented completely.
Therefore, it is required to increase the elastic recovery for long time operation in extreme environments i.e. high temperature, radiation dose.
