Samar Mubarakmand

Dr. Samar Mubarakmand (Urdu: ; b. 17 September 1942; NI, HI, SI, FPAS) is a Pakistani nuclear physicist known for his research in gamma spectroscopy and experimental development of the linear accelerator.

He came to public attention as the director of the test teams responsible for the performing the Pakistan's first atomic tests (see Chagai-I and Chagai-II) at the Ras Koh Hills, located in Balochistan Province, Pakistan.

Prior to that, he was the project director of the Pakistani missile research and development program and supervised development of the Shaheen-I ballistic missile, and the Babur cruise missile programs.

Samar Mubarakmand was born in Rawalpindi on 17 September 1942 to a Punjabi family from Hoshiarpur, East Punjab.

He gained his education in Lahore and matriculated from St. Anthony's High School in 1956.

After passing the university entrance exams, he enrolled at Government College University (GCU) where he studied physics under Tahir Hussain.

In 1960, he graduated with a Bachelor of Science (BSc) in physics with a concentration in experimental physics and a minor in mathematics.

During his college years, Mubarakmand was an avid swimmer and represented GCU at the National Games of Pakistan.

He conducted research in experimental physics under Hussain and built an experimental apparatus for his master's thesis.

His thesis contained detailed work on gamma ray spectrometry and performed an experiment that was witnessed by nuclear physicist Denys Wilkinson as part of his master's program.

Wilkinson spoke highly of his work and invited Mubarakmand to visit Oxford University in the United Kingdom to resume studies in experimental physics.

In 1962, Mubarakmand gained a Master of Science (MSc) in physics after publishing his thesis, "Construction of a gamma-ray spectrometer," under Hussain.

In 1962, he joined the Pakistan Atomic Energy Commission (PAEC) and gained a scholarship to study at Oxford University.

Recommended by Wilkinson, he was admitted there and joined the group led by Wilkinson.

At Oxford Mubarakmand participated in preparing a 22 million volt particle accelerator and was part of the team that commissioned it.

During his time at Oxford, Mubarakmand learned about linear accelerators, and after returning to Pakistan he built one.

Apart from studying, Mubarakamand played cricket and fast bowled for the Oxford University Cricket Club.

In 1966, Mubarakmand completed his doctoral thesis under Wilkinson and was awarded a Doctor of Philosophy (DPhil) in experimental particle physics.

After returning to Pakistan, Mubarakmand rejoined PAEC, and also joined the faculty of GCU as an assistant professor of physics in 1966.

Upon returning to Pakistan, Mubarakmand did fundamental work on neutron spectroscopy but later moved on to the Pakistan Institute of Nuclear Science and Technology (PINSTECH) to do post-doctoral research and joined the physics department led by Naeem Ahmad Khan in 1966.

In 1967, he joined the 'Nuclear Physics Group' (NPG) formed by Naeem Ahmad that consisted of Bashiruddin Mahmood and Hafeez Qureshi, a mechanical engineer.

At PAEC, Mubarakmand additionally worked towards applications involving chemical engineering where he built his reputation among his senior scientists.

The NPG worked towards engineering problems involving reactor physics and methods involving gas centrifuges, but the group did not last long together when Qureshi went to join the Radiation and Isotope Applications Division (RIAD) in 1971.

In January 1972, Mubarakmand was assigned to the Nuclear Physics Division (NPD), led by Ishfaq Ahmad, where he immersed himself in work on the physics calculations of implosion method nuclear weapons.

In 1973, Mubarakmand commenced the work on calculations involving the 'relativity of simultaneity'– a key concept involving investigating detonation of the weapon from several points at the same time.

However, the work was passed to the Theoretical Physics Group (TPG) as as it involved complex ideas of theoretical physics and Albert Einstein's Special and General relativity.

From 1974 to 1977, he taught physics at GCU and during his tenure as professor.

After India announced the surprise 'Smiling Buddha' nuclear test in 1974, PAEC accelerated the program by establishing the Fast Neutron Physics Group (FNPG) on the advice of Abdus Salam.

Munir Ahmad Khan made Mubarakmand its first director due to his expertise in chemical engineering and experimental physics.

The FNPG generated work calculating the neutron temperature, neutron initiator, and helping design the neutron reflector.

During the same time, he collaborated with Hafeez Qureshi to assist in designing the tamper and further helped conclude the calculation of the neutron energy's distributive ranges and the power produced by the neutrons, after the detonation process.

In 1978, Mubarakmand built a linear particle accelerator at PINSTECH to conclude solutions in the neutron generator.

He later witnessed the establishment of domestically developed supercomputer facilities at PINSTECH to help conduct the subcritical testing.

Due to his foremost experience in experimental physics, Mubarakmand was appointed director of the Diagnostic Group– a secretive division at PAEC that was charged with conducting experimental tests of atomic weapons and responsible for the countdown of the detonation process.

A comprehensive work of civil engineering that took place for potential tests sites was completed in a span of five to six years.

A milestone was reached on 11 March 1983 when Mubarakmand led the testing teams to supervise the secretive Kirana-I, their first 'cold' test.

Although the countdown and experiment was supervised by Mubarakmand, the blast effect was eventually determined by the Theoretical Physics Group.

Mubarakmand was the founding chairman of the National Engineering and Scientific Commission (Nescom) from 2001 until 2007.

He was subsequently appointed by the Government of Pakistan to assist the Thar coalfield project.

He is Voluntarily Heading the Mineral Exploration work in district Chiniot as Chairman Board of Directors Punjab Mineral Company, (M&M Deptt) Government of Punjab.
