Dear Jefferson Lab User Community,

As you know, we encountered severaldifficultiesduring beam restoration 
and re-start of the four-Hall physics program. As a result, we resumed 
physics operations September 26th rather thanonAugust 22^nd as 
originally planned. This substantially delayed start to CEBAF beam 
delivery requires us to adjust the scheduled experimental physics 
program accordingly.

Please find attached the adjusted beam schedule for the remainder of 
calendar year 2018. The constraints imposed by four-Hall physics 
operations,such asthe energy choices a hall may have, makere-scheduling 
the physics program a difficult task.  We understand that this 
short-term schedule does not include all of the science shown in the 
previously released schedule.  We apologize to the various experiment 
and Hall collaborations that do not see your anticipated science 
reflected in this short term schedule.

We would like to reassure you that we are considering options to restore 
some of the lost physics run-time.  We will be in a position to provide 
an updated long-term schedule for the remainder of FY19 once we have 
completed our resource planning for FY19.

We would also like to emphasize that we are in the process of learning 
all that we can from this difficult start-up period in order to ensure 
that we avoid such difficulties in the future.  We recognize the 
difficulties that this period has brought about, and appreciate your 
support and patience.

Best Regards,

Stuart
