==Run Configuration==

* Beam energy: 11.632 GeV
* Solenoid on at 1350A. 
* Beam current: CW 1 nA-2μA, 250 MHz frequency. See [https://www.jlab.org/Hall-D/hd_safety.php/2017_F-2018_S/RSAD.pdf RSAD] for the RadCon limitations. 
** Regular running: 150 nA on 4.1&middot;10<sup>-4</sup> radiator
* Diamond radiators:
**J1a50 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(50 μm - 4.1&middot;10<sup>-4</sup> R.L., 4&times;4 mm&sup2;) - old crystal - excellent rocking curve
**<font color="red"><b>JD70-100</b> (58 μm - 4.8&middot;10<sup>-4</sup> R.L., 7&times;7 mm&sup2;) - new crystal - excellent rocking curve </font>
**JD70-105 (47 μm - 3.9&middot;10<sup>-4</sup> R.L., 7&times;7 mm&sup2;) - new crystal - good rocking curve 
**JD70-104 (17 μm - 1.4&middot;10<sup>-4</sup> R.L., 7&times;7 mm&sup2;) - new crystal - wider rocking curve - marginally usable

*Tagger quadrupole on (-4.2 A). 
* Collimator hole: 5 mm diameter with &asymp;50 &micro;m diamond radiators, may use 3.4 mm diameter with &asymp;20 &micro;m diamonds
* Target: LH2 target
