Spectrometers were constructed with nominal resolving power [lambda]/[Delta][lambda][le]22 000 at a Bragg angle of 45[degree] and were used to measure the temperature of ions produced and trapped in the Livermore electron-beam ion trap facility. A temperature in excess of 500 eV was found for heliumlike Ti[sup 20+] ions produced under standard operating conditions for spectroscopy. The temperature was reduced to 130 eV by lowering the trapping potential and electron-beam current. A description of the spectrometers and representative measurements are given.
