Abstract：
The simulation result of thermal distortion of DCM crystal indirectly cooled by liquid nitrogen(LN₂) at Shanghai synchrotron radiation facility (SSRF) has been reported. The source is U27 undulator. The maximum of power density at 24m is 60W/mm². We give the correlation of the slope error of crystal surface vs. Bragg angle, the convection film coefficient, the bulk temperature of LN₂ and total power absorbed by the first crystal, respectively. The slope error is less than 3 arcsec when the Bragg angle is less than 30°, the thickness of crystal is larger than 30mm, the current of storage ring is up to 400mA and cooled by 78K LN₂.
