Modern Nötrino Deneylerinde Nükleer Emülsiyon Teknolojisi

Abstract

Nükleer emülsiyon, parçacık fiziği deneylerinde kullanılan önemli bir parçacık algıcıdır. Bu tekniğin kullanımı 1900’lü yıllarda başlamış ve günümüze kadar ilerleyerek gelmiştir. Nükleer emülsiyon, sahip olduğu yüksek uzaysal çözünürlüğü sayesinde yüklü parçacıkların izlerinin takip edilmesini kolaylaştırmaktadır. Ayrıca üç boyutlu etkileşimlerin görüntülerini yeniden oluşturma, hatta enerji ve momentum ölçümlerinin yapımına da olanak sağlamaktadır. Bu özellikleri nedeniyle teorik ve deneysel parçacık fiziğine önemli katkılar getirmektedir. Günümüzde nükleer emülsiyon tekniği halen çeşitli araştırmalarda geliştirilerek kullanılmaktadır. Tasarlanan yeni deneylerde nükleer emülsiyonlar hızlandırıcılarda oluşturulan parçacık demeti önüne yerleştirilerek elde edilen verilerden atom altı parçacıklar, birbirleriyle olan ilişkileri, etkileşimleri ve karakteristik özellikleri belirlenmeye çalışılmaktadır. Bu amaçla gerçekleştirilen deneyler arasında CHORUS, DONUT, PEANUT ve OPERA deneyleri bulunmaktadır. Nötrinonun doğasını anlamak üzere tasarlanan bu deneylerde nükleer emülsiyon teknolojisi başarıyla kullanılmış ve henüz tasarım aşamasına olan SHIP deneyinde de yine nükleer emülsiyon teknolojisinin kullanılması planlanmaktadır. Bu çalışmada parçacık fiziğinde yaygın kullanımı ve büyük önemi olan nükleer emülsiyon teknolojisinin gelişim aşamaları, kullanılan materyal ve yöntemler modern nötrino deneyleri ışığında incelenmiştir. Önümüzdeki yıllarda nükleer emülsiyon teknolojisinin giderek gelişeceği, yeni nesil deneylere ve araştırmalara yön vererek parçacık fiziğinde önemli sonuçlara ulaşılması beklenmektedir.

Nuclear Emulsion Technology in Modern Neutrino Experiments

Abstract

Nuclear emulsion is an important particle detector, used in particle physics experiments. The use of this technique began in the 1900s and developed up to day. Because of its high spatial resolution, the nuclear emulsion makes it easy to follow the tracks of charged particles. Also allows to reconstruct images of three-dimensional interactions and even to make energy and momentum measurements. Because of these features, it brings important contributions to theoretical and experimental particle physics. Today, nuclear emulsion technique is still being developed and used. In the new designed experiments, nuclear emulsions are placed in front of the beam of particles created in accelerators, and it is aimed to clarify the relations, interactions and characteristic features of subatomic particles. For this purpose, the CHORUS, DONUT, PEANUT and OPERA experiments were carried out to understand the nature of the neutrino particle. The nuclear emulsion technology has been used successfully applied in these experiments and the SHIP experiment, which is still in the design phase, nuclear emulsion technology will be used. In this study, the development stages of nuclear emulsion technology, which are widely used in particle physics, the materials and methods used are examined in the light of modern neutrino experiments. In the coming years, it is expected that nuclear emulsion technology will gradually develop and important results will be achieved in particle physics by directing new generation experiments and researches.
