The Global Arbitration Review has published an extensive discussion of the cross examination of experts by David Roney of  Sidley Austin LLP.

An excerpt:

Ask only one fact per question. Keep each question short and use simple words. Ideally, use the expert’s own words to make your point, rather than characterising or paraphrasing. Avoid all adjectives or quibble words. This is essential for control and clarity when covering complex technical subjects.

Listen carefully to the answer, and follow up. Do not be fixated on the next question in your notes. Make certain that you obtain the answer you want before moving to the next point.

At the beginning of the cross-examination or possibly at the beginning of different chapters, it may be necessary to destroy certain ‘safe havens’ that the expert witness could use to evade damaging lines of questioning. For example, you may need to establish that the expert witness reviewed certain key documents or was aware of particular facts before you will be able to obtain helpful admissions.”
