Abstract

Several recent modifications to the Cambridge University 600 kV HREM have resulted in increased levels of performance and greater operating efficiency. Changes include new Permendur pole‐pieces with a reduced gap leading to improved aberration coefficients, and an attachment to the tilt/shift supplies which facilitates accurate beam alignment. Resolution figures include: (a) an axial CTF extending, without zeros, beyond 1·8 Å at 575 kV; (b) tilted beam CTFs extending beyond 1·1 Å; and (c) lattice fringes of 0·72 Å spacing. 1983 Blackwell Science Ltd
