Power of Attorney

I, Phillip Febbo, hereby constitute and appoint Gary E. Bischoping,
Michael Dunn, Anshul Maheshwari, Magnus Momsen, John W. Kuo, David Shin,
Julie Wong and each of them individually, as my true and lawful
attorney-in-fact to:

1. Prepare, execute in my name and on my behalf, and submit to
the U.S. Securities and Exchange Commission (the "SEC") a Form
ID, including amendments thereto, and any other documents
necessary or appropriate to obtain codes and passwords enabling
me to make electronic filings with the SEC of reports required
by Section 16(a) of the Securities Exchange Act of 1934 or any
rule or regulation of the SEC.

2. Complete and execute on my behalf as an officer and/or director
of Varian Medical Systems, Inc. (the "Company") any Forms 3, 4,
or 5, and any amendment thereto, required to be filed by me under
Section 16(a) of the Securities Exchange Act of 1934 and the
rules and regulations thereunder.

3. Do and perform any and all acts for and on my behalf which may
be necessary or desirable to complete any such Form 3, 4 or 5,
and any amendment thereto, and timely file such form or amended
form with the SEC and any stock exchange or similar authority; and

4. Take any other action of any type whatsoever in connection
with the foregoing, which in the opinion of such attorney-in-fact
may be of benefit to, in the best interest of, or legally required
of me, it being understood that the documents executed by such
attorney-in-fact on my behalf pursuant to this Power of Attorney
shall be in such form and shall contain such information as such
attorney-in-fact may approve in such attorney-in-fact's discretion.

I hereby grant to each of such attorneys-in-fact full power and
authority to do and perform any and every act which is necessary
or desirable to be done in the exercise of any of the powers and
authority granted in this Power of Attorney, with full power of
substitution and revocation, and I ratify and confirm every act
that such attorney-in-fact lawfully performs or causes to be
done by virtue of this Power of Attorney and the powers and
authority granted herein.

I acknowledge that the attorneys-in-fact appointed in this Power
of Attorney, in serving in such capacity at my request, are not
assuming, and the Company is not assuming, any of my
responsibilities to comply with Section 16 of the Securities and
Exchange Act of 1934 or the rules or regulations thereunder.

This Power of Attorney shall remain in full force and effect until
I am no longer required to file Forms 3, 4 or 5 with respect to
my holding or transactions in securities issued by the Company,
unless I earlier revoke this Power of Attorney in a signed writing
delivered to the foregoing attorneys-in-fact.

IN WITNESS WHEREOF, the undersigned has executed this power of
attorney as of this 16th day of August, 2019 at the Corporate
Headquarters of Varian Medical Systems, Inc., Palo Alto, Califonia.
