Samar Mubarakmand (Urdu: ثمر مبارک مند; born 17 September 1942; NI, HI, SI, FPAS) is a Pakistani nuclear physicist, known for his research in gamma spectroscopy and the experimental development of the Charged Particle Accelerator at the Pakistan Institute of Nuclear Science & Technology (PINSTECH).

[9] 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.

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

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

[14] From 1974 to 1977, he was Director at Center for Advanced Studies in Physics (CASP) at Government College University, Lahore on temporary attachment.

Mubarakmand was Munir Khan, Chairman Pakistan Atomic Energy Commission’s first choice, to appoint him as head of the Diagnostic Group.

The Diagnostic Group also accomplished the important task of designing and manufacturing a neutron trigger source [20] based on fusion reactions.

He supervised and modernized the method of working at his new assignment and within the short period of three years more efficient, powerful and compact nuclear devices were produced to meet the varied requirements of Pakistan’s Fighter Aircraft as well as the upcoming delivery systems of different types.

During the five year tenure, Mubarakmand, apart from looking after the classified side of the Technical Program of PAEC, also became responsible for the optimal functioning of the centers of Nuclear Medicine, Agriculture, PINSTECH and New Labs.

At the last mentioned facility, Mubarakmand and an outstanding team of PAEC’s Scientists and Engineers were able to establish and commission Pakistan’s first reprocessing Plant for burnt reactor fuel.

Mubarakmand supervised the installation of Diagnostic Equipment and other facilities at the Site relevant to the safe conduction of the Nuclear Tests.

In 2005, Mubarakmand eulogized his memories in an interview with Hamid Mir's Capital Talk television show and said: I visited the first weapon-testing laboratories (WTL) at (Chagai District) for the first time in 1981....

(Abdul Qadeer) came at the invitation of the Chairman of the PAEC, Ishfaq Ahmad, and (Abdul Qadeer) arrived 15 minutes prior to the (science) experiments that were to be conducted...Recalling Munir Ahmad Khan and PAEC's role and its relation to the atomic bomb project priority dispute, Mubarakmand later said that: As many as nineteen steps were involved in the making of a nuclear weapon ranging from exploration of uranium to the finished device and its trigger mechanism.The technological and manpower infrastructure for eighteen out of these nineteen steps were provided by PAEC under the leadership of Munir Ahmad Khan who led it for nearly two decades from 1972 to 1991.

The tests however, were not publicly announced because of the international environment of stiff sanctions against countries, which sought to acquire nuclear capability....In 1990s, Mubarakmand took special initiatives in the advancement of the space program and led a team of engineers to successfully develop the Shaheen-I missile.

[25] He was the founding director of the National Defence Complex (NDC) bureau that initiated the work on the Shaheen-I and gathered support for the program.

[33] He lobbied heavily for the implementation of the Thar coal project initiated by the Provincial Government of Sindh despite strong public criticism by Abdul Qadeer Khan.

When speaking to a large crowd at Cadet College Fateh Jang, he said that he had developed a solution to the growing power outage and was now waiting for the government to put it into action.

[1] The Tethyan Cooper Company (TCC) has approached the High Court of Justice in the British Virgin Islands for the enforcement of the $5.97 billion award against Pakistan by the International Centre for Settlement of Investment Disputes (ICSID) in the Reko Diq case in Dec-20.

He had also maintained Reko Diq and other gold reserves in the country will bring in $131 billion to the national exchequer in life of mine, 56 years.
