To help Users better plan their experiments, a list of '''typical''' time estimates for established tuning procedures is shown below.
These estimates should be used by the User to budget the necessary overhead for experimental start-up,
energy changes, species changes...
 
[Ask Bob about species changes! 
Ask Bob about start-up!]
 
In addition, interruptions to beam delivery may occur. 
Some of these interruptions, such as those due to regular maintenance or proton therapy, are known at the time the
[http://www.triumf.info/facility/experimenters/schedules/schedule.php Beam Schedule]
is prepared and scheduled accordingly.  Others, such as work in the ISAC Target Hall, may not be known at the time of scheduling but are known on a time scale of weeks in advance.  The Beam Delivery group will try to meet with the experimental spokesperson(s) prior to the beginning of an experiment to confirm what is required from a beam delivery standpoint and to assist with the preparation of a detailed running plan, taking into account these known, but not scheduled, interruptions.  At ISAC, this planning may help a User decide the optimum time for an energy change or a species switch.  Totally unplanned interruptions, such as those due to mechanical failures, are unavoidable.  Because TRIUMF is a user facility, catering to many external experimenters, it is generally not possible to adjust the beam schedule in response to such interruptions.

The [http://www.triumf.info/facility/research_fac/yield.php ISAC Yield Measurements] database should be consulted for the measured intensities of available species.
 
All yields are measured at the ISAC Yield Station unless otherwise noted.
As such, the intensity delivered to any given experimental facility will depend upon the beam transport efficiency and the stripping efficiency, if needed.
'''Delivered yields will be lower, especially for post-accelerated beams.'''
 
Below is a table giving the approximate transmission to different experimental facility areas for given conditions.
The measured yield value should be multiplied by this factor to obtain an '''approximate''' value of what intensity may be expected at an
experiment facility.
 
Need the numbers for different areas and conditions (stripping, chopping, ...)
 
Do we mention that intensities drop over time (i.e. these should not be time-averaged expectations)?
